  • Patent number: 8643819
    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.
