Patent ID: 7110065

Claim:
A transmissive-type liquid crystal display (LCD) device, comprising: lower and upper substrates facing each other; a thin film transistor array having a pixel electrode within each pixel region defined on the lower substrate; a black matrix layer on the upper substrate corresponding to portions of the lower substrate, except for the pixel electrode; a color filter layer on the upper substrate corresponding to the pixel electrode of the lower substrate, the color filter layer having a first region transmitting red wavelengths of light, a second region transmitting green wavelengths of light, and a third region transmitting blue wavelengths of light, the first region includes photonic crystal balls having first diameters and second diameters different from each other, the second region includes photonic crystal balls having the first diameters and third diameters different from the first and second diameters, and the third region includes photonic crystal balls having the second diameters and the third diameters; and a liquid crystal layer between the lower and upper substrates.
