  • Patent number: 7321409
    Abstract: The invention provides a transflective liquid crystal device and an electronic apparatus using the same which do not cause a non-uniformity in the substrate gap, even though a layer-thickness adjusting layer is formed so that the layer thickness balance of a liquid crystal layer between a transmission display region and a reflection display region is optimized thereby. Below a counter electrode of a counter substrate of a transflective liquid crystal device, a color filter for transmission display, being thin and having a wide chromaticity region, is formed in a transmission display region, and a color filter for reflection display, being thick and having a narrow chromaticity region, is formed in a reflection display region. Further, the interval between a TFT array substrate and the counter substrate is adjusted by a columnar protrusion formed on the TFT array substrate, and a gap material is not dispersed between the TFT array substrate and the counter substrate.
