Abstract:
A liquid crystal device having a plurality of pixels that modulates light in accordance with a given image signal, the liquid crystal device comprising:an exit side substrate portion; an entrance side substrate portion opposed to the exit side substrate portion; a liquid crystal layer placed between the exit side substrate portion and the entrance side substrate portion; the exit side substrate portion comprising an exit side substrate, a first electrode that drives the liquid crystal layer formed on the exit side substrate, and an exit side cover arranged on an exit side with respect to the exit side substrate; the entrance side substrate portion comprising an entrance side substrate and a second electrode that drives the liquid crystal layer formed on the entrance side substrate; the exit side cover having an absolute value of a coefficient of thermal expansion of less than 37Ã—10âˆ’7/Â° C. to restrain deterioration in image quality due to thermal expansion of the exit side cover; and an exit side polarizer spaced apart from the exit side cover and held in place by a structure to maintain consistent spacing between the exit side polarizer and the exit side cover such that heat generated in the exit side polarizer does not cause deterioration in image quality of the liquid crystal panel due to thermal expansion of the individual components, such deterioration including deterioration in contrast or inconsistency in color generated at the four corners of the image.
