Abstract
A technique for providing a liquid crystal display device which has an excellent production yield but little orientation fault. A liquid crystal display device in which an orientation regulating member 108 including a trunk portion 108a and a branch portion 108b is formed between a seal member 112 and a liquid crystal 114 so that not only a mechanical strength is enhanced but also the liquid crystal molecules can be homogeneously arrayed to establish a satisfactory black level when no voltage is applied, thereby to improve the contrast.

A liquid crystal display device comprising:
- a pair of substrates;
- a seal material interposed between the pair of substrates;
- an orientation regulating member comprising a trunk portion formed along an inner side of the seal material and a branch portion protruded from the trunk portion;
- and
- a liquid crystal filling an inner side of the orientation regulating member,
- wherein at least one of the pair of substrates is transparent.
