Patent ID: 8035784

Claim:
A semi-transmissive liquid crystal display device, which is formed by sealing liquid crystal of negative dielectric anisotropy between first and second substrates and has a transmission region controlling transmitted light and a reflection region controlling reflected light, comprising: a transparent electrode disposed in the transmission region of the first substrate; a reflecting electrode disposed in the reflection region of the first substrate; a first vertical orientation film covering surfaces of the transparent electrode and the reflecting electrode; a common electrode which is formed on the second substrate and faces the transparent electrode and the reflecting electrode; and a second vertical orientation film covering a surface of the common electrode, wherein only the second vertical orientation film and the first vertical orientation film on the transparent electrode are modified by light, and further wherein a pretilt angle of liquid crystal molecules on an interface of the first vertical orientation film on the transparent electrode, a pretilt angle of liquid crystal molecules on an interface of the second vertical orientation film in a region opposed to the transparent electrode and a pretilt angle of liquid crystal molecules on an interface of the second vertical orientation film in a region opposed to the reflecting electrode are 45° or more, and are smaller than a pretilt angle of liquid crystal molecules on an interface of the first vertical orientation film on the reflecting electrode, and the liquid crystal molecules in the transmission region are subjected to bend orientation.
