In a liquid crystal display device, one or a plurality of partition walls adhering to the two substrates are provided in a region between the adhesive member for sealing the peripheral portions of the two substrates and a display region located inside the adhesive member so as to reduce stress applied to the liquid crystal substance. Even when stress is applied to the liquid crystal substance in the peripheral portion of the substrate, the stress is reduced by the partition wall and is not transmitted to the display region on the opposite side of the partition wall. Therefore, even when a crack occurs in the peripheral portion of the substrate due to the stress, the propagation of the crack is stopped by the partition wall, and the crack does not enter the display region.
