Transflective liquid crystal display device
First Claim
1. A transflective liquid crystal display device including a liquid crystal display panel having a pair of substrates and a liquid crystal layer put between the pair of substrates, in which the liquid crystal display panel has a plurality of sub-pixels each having a transmission portion and a reflection portion, and each of the plurality of sub-pixels has a pixel electrode and a counter electrode, wherein:
- in each of the sub-pixels, the pixel electrode is in common with the transmission portion and the reflection portion, the counter electrode is independent between the transmission portion and the reflection portion;
a clearance extending to separate the counter electrode of the transmission portion and the counter electrode of the reflection portion;
the potential applied to the counter electrode is different between the transmission portion and the reflection portion;
the liquid crystal layer comprises positive type liquid crystals; and
the liquid crystal initial alignment direction of the liquid crystal layer is in a direction perpendicular to an extending direction of the clearance between the counter electrode of the transmission portion and the counter electrode of the reflection portion, or in a direction within a range of ±
2°
in a clockwise direction relative to the direction perpendicular to the extending direction of the clearance.

Abstract
A transflective liquid crystal display device with improved display quality in which the liquid initial alignment direction of the liquid crystal layer is in a direction perpendicular to the extending direction of a clearance between the counter electrode of a transmission portion and a counter electrode of a reflection portion or in a direction within a range of ±2° in the clockwise direction perpendicular to the extending direction of the clearance in a case where the liquid crystal layer comprises positive type liquid crystals, or the liquid crystal initial alignment direction of the liquid crystal layer is in a direction parallel with the extending direction of a clearance, or a direction within a range of ±2° in the clockwise direction relative to the extending direction of the clearance in a case where the liquid crystal layer comprises negative type liquid crystals.
