DISPLAY DEVICE, OPTICAL MODULE AND PROJECTION DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress deterioration in image quality in a display device and degradation in the function of the display device by exactly measuring temperature of a layer to be driven in the display device. SOLUTION: The display device 1 is equipped with a drive substrate (silicon drive substrate 20) equipped with a drive element corresponding to a pixel, the layer to be driven (liquid crystal 30) provided on the drive substrate (silicon drive substrate 20), and a temperature detection means (temperature sensor 50) provided in the area of the layer to be driven (liquid crystal 30) on the drive substrate (silicon drive substrate 20).
