Abstract: A manufacturing method by which a plurality of liquid crystal cells are obtained from mother substrates includes a step of, before applying a sealing material, forming a columnar member disposed in a direction crossing a side of a second mother substrate, wherein the columnar member includes on one end side a first member disposed adjacent to an extended portion constituting a liquid crystal sealing inlet of the sealing material and at the other end a second member disposed to face at least the extended portion of the sealing material along the direction of the side, and the application of the sealing material is performed such that the extended portion of the sealing material rides on a part of the first member of the columnar member.

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.

Abstract: The TFT substrate includes a conductive region electrically conducted to the transparent conductive film and a terminal region, on a first side not covered with the counter substrate. The terminal region includes a ground terminal connected to the conductive region and an adjacent terminal which is adjacent to the ground terminal and supplies signals or power source to the peripheral circuit. The adjacent terminal is connected to the peripheral circuit through a first wiring installed along a third side of the TFT substrate toward a second side facing the first side. The first wiring is extended to a middle point of the third side and then connected to the peripheral circuit.
