The present invention relates to a backlight assembly and a display device having the same, and more particularly, to a backlight assembly and a display device having the same for improving display quality of an image.

A liquid crystal display (LCD), which is one of flat panel displays, displays an image by using electrical and optical characteristics of a liquid crystal. The liquid crystal display (LCD) is thinner and lighter than other display devices, and has a low power consumption and a low driving voltage.

The liquid crystal display (LCD) includes a liquid crystal display panel for displaying an image by using light transmittance of liquid crystal and a backlight assembly for providing light to the liquid crystal display panel.

The backlight assembly employed in the liquid crystal display is classified into an edge type backlight assembly and a direct type backlight assembly according to a position of a light source for generating light.

The edge type backlight assembly includes a lamp for generating light, a light guide plate disposed to face the side of the lamp, and a storage container for accommodating the lamp and the light guide plate, the path of the light generated from the lamp through the side of the light guide plate. It guides and exits to the said liquid crystal display panel.

The direct type backlight assembly includes a plurality of lamps disposed below the liquid crystal display panel, a storage container accommodating the lamps, a diffusion plate disposed on the upper surfaces of the lamps, and a reflecting plate disposed on the lower surfaces of the lamps. Light generated from the lamps is diffused by the diffusion plate and is incident to the liquid crystal display panel.

The direct backlight assembly further includes a lamp supporter for supporting the lamps. In general, as the lamp has a rod-cylindrical shape, the lamp supporter has a U-shaped ring shape to enclose a portion of the lamp. As such, as the lamp supporter wraps a portion of the lamp, the lamp supporter is in contact with the portion of the lamp in a large area.

However, when the lamp is in contact with the lamp supporter in a large area, heat generated in the lamp is conducted to the lamp supporter through the contact portion. The conduction of heat through the contact portion can cause the temperature of the lamp to be locally lowered, resulting in a dark portion visible in the appearance of the liquid crystal display. As a result, generation of the dark portion lowers display quality of the liquid crystal display.

Therefore, the technical problem of the present invention is derived to solve the conventional problems, and an object of the present invention is to provide a backlight assembly that improves the display quality of the image by minimizing the amount of heat conduction.

Another object of the present invention is to provide a display device having the above-described backlight assembly.

In order to achieve the object of the present invention, the backlight assembly according to the first embodiment includes a container, a plurality of lamps, and a lamp support member.

The storage container includes a bottom portion and a side portion to form a storage space. The plurality of lamps are arranged in parallel to each other inside the receiving container to generate light. The lamp support member is disposed inside the storage container, and includes a supporter lamp ring for supporting the lamp and a supporter plate coupled to the supporter lamp ring to fix the supporter lamp ring.

The backlight assembly according to the second embodiment, which is derived to achieve the object of the present invention includes a container, a plurality of lamps and a lamp support member.

The storage container includes a bottom portion and a side portion to form a storage space. The plurality of lamps are arranged in parallel to each other inside the receiving container to generate light. The lamp support member includes a support body portion disposed inside the storage container and formed in a direction crossing the lamp, and a lamp ring portion protruding from an upper surface of the support body portion to surround the lamp.

In accordance with another aspect of the present invention, a display device includes a backlight assembly and a display panel.

The backlight assembly may include a storage container including a bottom portion and a side portion, a plurality of lamps disposed in parallel with each other on a bottom portion of the storage container to generate light, and a lamp support member coupled to the bottom portion to fix the lamps. It includes. And a display panel disposed on the backlight assembly to display an image by using light generated by the backlight assembly. The lamp support member includes a supporter lamp ring for wrapping and supporting the lamp and a supporter plate coupled to the supporter lamp ring to fix the supporter lamp ring.

According to the present invention, as the lamp is penetrated and supported by the lamp support member, the lamp and the lamp support member can be in contact with each other with a minimum area, and as a result, the lamp is locally lowered in temperature, resulting in uneven brightness. It is possible to further improve the display quality of the image.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<First Embodiment of Backlight Assembly>
