Abstract
The invention provides a semi-transparent reflective electro-optic apparatus capable of increasing a quantity of display light in either of the reflection mode and the transparent mode, and electronic equipment including the same. In a TFT array substrate of a reflective electro-optic apparatus, the back surface of a light-reflecting film includes a light-guiding reflection surface that reflects and guides light incident from the back surface side of a light-transmitting substrate to the surface of the light-reflecting film opposing the light-guiding reflection surface with a light-transmitting window in between. Hence, of the light incident from the back surface side of the light-transmitting substrate, light that is shielded in the related art by the light-reflecting film and does not contribute to display in the transparent mode is partly reflected on the light-guiding reflection surface and thereby contributes to display.
