ABSTRACT:
A liquid crystal layer is provided between a pair of substrates, one of the pair of substrates is provided with a pixel region including a TFT and a light shielding layer in which an opening portion is formed, a semiconductor layer composing the TFT is overlapped with the light shielding layer and formed along one side of the opening portion, and an alignment of a liquid crystal molecule is controlled such that light which transmits through the liquid crystal layer is incident as polarized light perpendicular to the one side of the opening portion. The liquid crystal layer is particularly made of more a TN mode liquid crystal.
