Abstract:
1. A liquid crystal display (LCD) device comprising: a back light assembly that generates a first light; a liquid crystal display panel including an upper substrate, a lower substrate facing the upper substrate, and a liquid crystal layer interposed between the upper substrate and the lower substrate, the liquid crystal display panel receiving the first light generated from the back light assembly to display an image; a first polarizing plate disposed on the upper substrate; a selective reflection polarizing plate disposed on the first polarizing plate, the selective reflection polarizing plate reflecting a portion of an external light; and a second polarizing plate disposed on the lower substrate, wherein the upper substrate includes color filters arranged in a matrix formation and a black matrix disposed between the color filters, wherein the black matrix comprises a material selected from the group consisting of aluminum (Al), aluminum alloy, chromium (Cr), titanium (Ti), tantalum (Ta) and a mixture thereof, and wherein the black matrix reflects the external light that it receives through the selective reflection polarizing plate and the first polarizing plate.
