Abstract

The liquid crystal display device according to one embodiment of the present invention comprises: a liquid crystal panel; a transparent window disposed over the liquid crystal panel; a light shielding pattern formed in the peripheral region of the transparent window; and an optical converting layer formed in the internal area of the transparent window, where the light shielding pattern is not formed, to change the characteristics of light from an external source incident from above.
