The display panel, the manufacturing method thereof and the display device of the present invention are described in further detail with reference to the embodiments of fig. 1 to 9.
As shown in fig. 1 to 4, a display panel includes:
a first substrate and a second substrate;
an active switch formed on the first substrate;
a color filter layer formed on the first substrate or the second substrate;
the display control layer is arranged between the first substrate and the second substrate;
the color filter layer includes a plurality of color resistors 31, the color resistors 31 include a first color resist film 32 and a second color resist film 33, the first color resist film 32 and the second color resist film 33 are disposed on the same color resistor 31, and the thickness of the first color resist film 32 is greater than that of the second color resist film 33.
The thickness of the first color resistance film is designed to be larger than that of the second color resistance film 33, so that the problem of color cast of a large visual angle can be effectively solved, the problem of gray scale whitening in the display panel can be effectively suppressed in the large visual angle, the display effect of the display panel is better, and the display quality of the display panel is further improved; moreover, by utilizing the pixel distinguishing effect caused by the thicknesses of the different color resistors 31 in the display control layer 13, the effect of low color cast can be effectively achieved, the color and the brightness of the display panel are ensured to be more uniform, and the display quality of the display panel is effectively improved; meanwhile, the thickness of the first color resist film 32 is larger than that of the second color resist film 33, so that the material consumption for manufacturing the color filter layer 30 can be effectively saved, the production cost of the display panel is further reduced, and the market competitiveness of the display panel is better improved; the first color resist film 32 and the second color resist film 33 are arranged on the same color resist 31, so that the first color resist film 32 and the second color resist film 33 can be manufactured at the same time, the same materials and processes are adopted for setting, the production cost of the display panel can be effectively saved, and the display panel only needs to be manufactured at the same time by adopting a multi-tone photomask as required; the display control layer 13 includes a liquid crystal layer, and the liquid crystal display has a working principle that liquid crystal molecules are placed between two parallel glass substrates, and a driving voltage is applied to the two glass substrates to control the rotation direction of the liquid crystal molecules, so as to refract the light of the backlight module to generate a picture.
The thickness difference between the first color resist film 32 and the second color resist film 33 is 0.3-0.5 μm, the transmittance of the backlight passing through the first color resist film 32 is small when the backlight passes through the first color resist film 32 with the thickness of d1 to form a pixel light-transmitting dark area, and the transmittance of the backlight passing through the second color resist film 33 with the thickness of d2 is large to form a pixel light-transmitting bright area, so that the display panel achieves the effect of low color cast, the display effect of the display panel is better, and the display quality of the display panel is further improved; moreover, the thickness difference between the first color resist film 32 and the second color resist film 33 can be formed by adjusting the conventional manufacturing process and using the multi-tone mask 40 for manufacturing the color filter layer 30, so that the break difference between the first color resist film 32 and the second color resist film 33 can be conveniently formed; compatible with the conventional process flow, the multi-tone mask 40 can effectively control the thickness difference between the first color resist film 32 and the second color resist film 33 within the range of 0.3 to 0.5 μm by only changing the developing process of the color filter layer 30.
The orthographic projection area of the first color resistance film on the substrate 10 is larger than that of the second color resistance film on the substrate 10, and when a backlight module source irradiates the color resistance 31, the display color of the pixel is more uniform by properly adjusting the area ratio of the first color resistance film 32 to the second color resistance film 33 on one pixel, so that the condition of over brightness or over darkness is avoided, the problem of gray scale whitening in effective suppression is solved, and the better display effect of the display panel is ensured; when the liquid crystal display panel is applied to a Multi-domain Vertical Alignment (MVA) panel, because the Multi-domain Vertical Alignment panel makes the liquid crystal static not in a traditional Vertical manner but in a certain angle by using the protrusions, the liquid crystal static is biased to be static, the view angle is wider, the increase of the view angle can reach more than 160 degrees, and the problem of medium gray scale whitish when the large view angle is displayed can be effectively solved; the multi-domain vertical alignment panel is faster when a voltage is applied to change the liquid crystal molecules to be horizontal so as to allow the backlight to pass, thereby greatly shortening the display time and shortening the display response time.
