ABSTRACT:
An electro-optical device includes three sub-pixels each having a transmitting region and a reflecting region in which a coloring layer having one color among three colors is respectively included and corresponding to the three respective colors and at least one sub-pixel in which a coloring layer having one color other than the three colors is disposed in the transmitting region. In the transmitting region, transmission display is performed and in the reflection region, reflection display is performed. A color display is performed by the reflection display or the transmission display, and one pixel is formed as a display unit by using the transmitting regions of the three sub-pixels corresponding to the three colors and at least one sub-pixel and the reflecting regions of the three sub-pixels corresponding to the three colors.
