Liquid crystal display device and manufacturing method thereof

摘要

It is possible to separate each liquid crystal display panel from a mother board in which multiple liquid crystal display panels are formed even with a thin glass substrate, by forming a columnar spacer in the boundary between liquid crystal display panels, forming a scribe line corresponding to the columnar spacer on both sides of the counter substrate and the TFT substrate in the mother board, and forming a separation line between the scribe lines by applying a bending stress to the mother board. Since the columnar spacer is formed in a portion corresponding to the scribe line, the strength in this portion increases, so that the proper scribe lines and break lines can be formed when the thickness of the glass substrate is reduced to about 0.15 mm.

主权项

1. A liquid crystal display device comprising:
a TFT substrate including a plurality of pixels arranged in a matrix; a counter substrate disposed opposite the TFT substrate; a plurality of spacers disposed on the counter substrate; a sealing material bonding the TFT substrate and the counter substrate; and a liquid crystal sealed between the TFT substrate and the counter substrate by the sealing material; wherein the TFT substrate is made larger than the counter substrate to form a terminal portion on a single layer of the TFT substrate, wherein a spacer of the plurality of spacers or a portion of the spacer is present in an end portion of the liquid crystal display device, wherein the sealing material is present between the liquid crystal and the spacer or the portion of the spacer, wherein the sealing material is not present in the end portion of the liquid crystal display device, wherein the spacer or the portion of the spacer does not contact with the TFT substrate in end portions of three sides of the counter substrate other a side of the counter substrate facing the terminal portion of the liquid crystal display device, wherein another spacer of the plurality of spacers or a portion of the another spacer formed at an end portion of the counter substrate facing the terminal portion is in contact with the TFT substrate.
