Patent ID: 8164720

Claim:
A liquid crystal display apparatus comprising: a liquid crystal display panel including a first substrate, a second substrate, a liquid crystal layer held in a sandwiched condition between the first and second substrates, and a pixel electrode and a common electrode disposed on the second substrate in order to drive the liquid crystal layer; a backlight disposed on one face of the liquid crystal display panel; a first polarizer disposed on one face of the first substrate, at a side opposite to the second substrate; and a second polarizer disposed on one face of the second substrate, at a side opposite to the first substrate; wherein the liquid crystal layer has a property of generating optical anisotropy from an optical isotropic state when a voltage is applied; wherein the liquid crystal display panel includes a transmission area and a reflection area in one pixel; wherein in the reflection area, one of the pixel electrode and the common electrode is formed into a comb shape or includes a slit-shaped aperture in an electrode layer formed into a planar shape, with an other electrode of the pixel electrode and the common electrode being formed planarly on a different layer via an insulation layer; wherein in the transmission area, the pixel electrode and the common electrode are formed into a comb shape on the same layer, the pixel electrode and the common electrode being further disposed at alternate positions, such that an electric field formed in the liquid crystal layer according to a particular voltage difference between the pixel electrode and the common electrode is weaker in the reflection area than in the transmission area; and wherein a thickness of the liquid crystal layer in the transmission area and a thickness of the liquid crystal layer in the reflection area are constant.
