Abstract
An electro-optic device is provided that is capable of preventing an interference of reflected lights from a light reflecting film and avoiding the occurrence of glare and chrominance non-uniformity among pixels, and an electronic apparatus using the electro-optic device. In a TFT array substrate of a reflective or transflective electro-optic device, a lower-side recess/projection forming film 13a, is formed in each of pixels 100a in the form of a matrix pattern so that a recess/projection pattern to scatter light is formed on the surface of a light reflecting film. The pixels are grouped into a plurality of units, each including a plurality of pixels, and the recess/projection pattern is formed to provide a different pattern for each pixel at least in each of the units. Different recess/projection patterns are obtained, for example, by rotating the recess/projection pattern for a pixel as a reference.
