Liquid crystal display panel and method of manufacturing the same

摘要

In one embodiment, a liquid crystal display panel includes an array substrate and a counter substrate each having a display region and a peripheral region arranged adjacent to the display region. A resin layer is formed either one of the array substrate and the counter substrate. A protrusion in the shape of a wall is arranged on the resin layer with a gap between the protrusion and the substrate opposing the protrusion. A seal material is formed between the array substrate and the counter substrate, and arranged between a peripheral portion of the display region and the protrusion for attaching the array substrate and the counter substrate. A liquid crystal layer is formed in a surrounded region by the array substrate, the counter substrate and the seal material.

1. A method of manufacturing a liquid crystal display panel including:
an array substrate including a display region and a peripheral region arranged adjacent to the display region; and a counter substrate including the display region and the peripheral region, and arranged opposing the array substrate with a gap therebetween; comprising: forming respective array patterns on a first array substrate and a second array substrate corresponding to a first display panel and a second display panel on a first mother glass substrate; forming respective counter patterns on a first counter substrate and a second counter substrate corresponding to the first display panel and the second display panel on a second mother glass substrate; forming a common insulating layer covering the peripheral regions of the first and second display panels on either one of the first and second mother glass substrates; forming a resin layer on the common insulating layer in the first and second display panels; forming a concave portion in the resin layer in the first and second display panels, respectively, by removing a portion of the resin layer; forming a first protrusion and a second protrusion of the wall shape above the common insulating layer; forming a plurality of pillar-shaped spacers between the array substrate and the counter substrate so as to have a gap therebetween; attaching the array substrate and the counter substrate by a seal material provided between the peripheral portion of the display region and the first and second protrusions, respectively, an outer edge portion of the seal material being accommodated in the concave portion; and cutting the first and second mother glass substrates in a region between the first protrusion and the second protrusion from external surfaces of the mother glass substrates.
