ABSTRACT:
A liquid crystal display device having a high quality able to prevent deterioration etc. of a liquid crystal panel even when a liquid crystal panel used in a light valve of a projector etc. is operated under a high temperature and high humidity environment and a projection type display apparatus using the liquid crystal display device, wherein a liquid crystal layer16is sandwiched between a pair of substrates formed by bonding a TFT array substrate11and a counter substrate12by a sealing material15so that they face each other across a predetermined gap, the sealing material15contains a nonconductive filler having a mean particle size of less than 0.5 μm, a liquid crystal material used in the liquid crystal layer16is set in its refractive index anisotropy an at room temperature to 0.16 or more, and a cell gap d of an interval between the TFT array substrate11and the counter substrate12is set at 3 μm or less.
