The purpose of the present invention is to provide a configuration that allows the corners of a sealing material to be appropriately cut. The liquid crystal display device is provided with a liquid crystal panel that includes: an annular sealing material that has a corner in plan view and is for sealing a liquid crystal layer between a first transparent substrate and a second transparent substrate; and a first panel cutting aid material that is embedded in the corner of the sealing material. The first panel cutting aid material has a height that matches the gap between the first transparent substrate and the second transparent substrate. The first panel cutting aid material has a surface that is exposed from the outer periphery of the sealing material.

Liquid crystal display device and production method for liquid crystal display device

A liquid crystal display includes a terminal substrate, an opposed substrate, a seal member and a protective wall. The terminal substrate includes: a display area which displays an image, a terminal which inputs an external signal to a wiring in the display area, and a connection conductor which electrically connects the wiring in the display area and the terminal. The opposed substrate includes a conductive film on a surface thereof. The seal member surrounds the display area and through which the terminal substrate and opposed substrate are attached with each other while being opposed with each other. The protective wall surrounds a proximity portion of the connection conductor and the conductive film outside of an area surrounded by the seal member, together with the seal member to isolate and protect the proximity portion from an outside.
