A liquid crystal display device of the present invention includes a liquid crystal interposed between a CF substrate that is an ultra-thin glass substrate and a TFT substrate, and a seal pattern having an injection port. Spacer structures are arranged such that the area density thereof is higher in a corner portion farther from the injection port than in a corner portion closer to the injection port.

Liquid crystal display device with main columnar spacers and sub columnar spacers having different area densities

The present invention includes liquid crystal held between an array substrate including a display area and a color filter substrate, a seal material pasting the both substrates together outside in plan view of the display area, and column spacers between the both substrates. The seal material includes a seal periphery surrounding the display area, and seal extending portions forming an injection port of the liquid crystal by extending the seal periphery outside in plan view of the display area from both end of a partial opening. The seal periphery includes no spacer therein, and the seal extending portions include spacers therein.
