Patent ID: 7580097

Claim:
A liquid crystal display panel comprising: a first substrate defining a plurality of unit pixels, each unit pixel comprising a red sub-pixel area, a green sub-pixel area, a blue sub-pixel area, and a white sub-pixel area; a second substrate defining a plurality of unit pixels, each unit pixel comprising a red sub-pixel area, a green sub-pixel area, a blue sub-pixel area, and a white sub-pixel area; a thin film transistor formed on the first substrate; a pixel electrode connected to the thin film transistor; a reflection electrode connected to the pixel electrode; red, green, and blue color filters formed in the red, green, and blue sub-pixel areas, respectively, of the second substrate; and a light hole formed in the second substrate exposing the white sub-pixel area of the second substrate and exposing at least a portion of a red sub-pixel area, a green sub-pixel area, or a blue sub-pixel area of the second substrate, wherein the reflection electrode is formed so as to occupy 100% of the white sub-pixel area.
