Abstract
A microlens substrate and a liquid crystal panel are attached with a liquid layer having a lower refractive index than that of a microlens interposed between them. This suppresses light amount loss caused by interface reflection. The liquid layer also prevents mixing of moisture or dust, which occurs when an air layer is interposed, and thereby improves the reliability of the device.
