摘要:
An LCD device in an LCD projector includes a TFT substrate, a counter substrate, an LC layer sandwiched between the TFT substrate and the counter substrate, and a pair of compensation substrates attached onto the outer surfaces of the TFT substrate and the counter substrate far from the LC layer. The compensation substrate has a negative coefficient of thermal expansion (CTE) for compensating the retardation caused by a temperature rise of the TFT substrate and the counter substrate due to irradiation thereof by a light source.
