Patent ID: 7839472

Claim:
A liquid crystal device comprising: first and second substrates which face each other; a liquid crystal layer interposed between the first substrate and the second substrate; a reflection display region which is provided in one region of a sub-pixel configuring a control unit of a driving display by the first and second substrates with the liquid crystal layer interposed therebetween and performs a display by reflected light; a transmission display region which is provided in the other region of the sub-pixel and performs a display by transmitted light; a layer thickness adjustment film which is provided on the second substrate in correspondence with the reflection display region and defines the thickness of the liquid crystal layer to be different from that in the transmission display region; and an alignment film which is provided between the second substrate and the liquid crystal layer so as to cover the layer thickness adjustment film and is subjected to a rubbing process, wherein the layer thickness adjustment film has a step difference surface at a boundary between the reflection display region and the transmission display region, and when the rubbing process is performed in a direction opposed to the step difference surface and an angle between an extending direction of the step difference surface and a rubbing direction is α, a relationship of 70°≦α≦110° is satisfied, and the rubbing process is in a same direction in the reflection display region and the transmission display region; first and second electrodes which are provided on the first substrate so as to generate an electric field; wherein the second electrode has a plurality of electrode lines which are arranged in parallel with gaps interposed therebetween; and when an angle between the gaps and the rubbing direction is β, a relationship of 5°≦β≦20° is satisfied.
