  • Patent number: 8040472
    Abstract: A multi-domain vertical alignment liquid crystal display that does not require physical features on the substrate (such as protrusions and ITO slits) is disclosed. Each pixel of the MVALCD is subdivided into color components, which are further divided into color dots. The polarity of the color dots are arranged so that fringe fields from adjacent color dots causes multiple liquid crystal domains in each color dot. Specifically, the color dots of a pixel are arranged so that each color dot of a first polarity has four neighboring pixels of a second polarity. Thus, a checkerboard pattern of polarities is formed. Furthermore, the checkerboard pattern is extended across multiple pixels in the MVALCD. In addition, many display unit include multiple pixel designs to improve color distribution or electrical distribution.

    Abstract: In a liquid crystal display device in which liquid crystal is sealed by a one drop fill method, the gap between a TFT substrate and a counter substrate is defined by a columnar spacer in a display region, and the gap between them is defined by a columnar spacer also in a seal portion. In the display region, one layer of a color filter is formed below the columnar spacer. In the seal portion, two layers of island-shaped color filters are formed. With this configuration, the gap between the TFT substrate and the counter substrate can be maintained equal between the display region and the seal portion. Even when the process for forming the columnar spacer varies, it is possible to eliminate a change in difference between the gap between the TFT substrate and the counter substrate in the display region and the gap in the seal portion.
