Abstract
The invention provides a transflective liquid crystal device and an electronic apparatus using the same to display images with a sufficient quantity of light in their use, even though a color filter for transmission display and a color filter for reflection display are formed in a pixel. On the surface of a counter substrate in a transflective liquid crystal device, a color filter for transmission display, with a wide chromaticity region, is formed in a transmission display region of the lower layer of the counter electrode, and a color filter for reflection display with a narrow chromaticity region is formed in a reflection display region. A boundary portion of the color filters is located inside the reflection display region.
