Liquid crystal display panel
View Patent ↗The present invention provides a liquid crystal display panel which exhibits excellent durability by protecting portions of a substrate which are liable to be most easily cracked or chipped. In a liquid crystal display panel arranging a sealing material between a TFT substrate and a CF substrate, and holding a liquid crystal layer between the TFT substrate and the CF substrate, the CF substrate has one-side surface thereof formed in a recessed shape as viewed from above, a flexible printed circuit board is connected to a region of the TFT substrate where the CF substrate and the TFT substrate do not overlap with each other, and a sealing material is formed along a shape of the CF substrate. Portions where the TFT substrate and the CF substrate overlap with each other and correspond to both sides of the portion where the flexible printed circuit board is arranged can be formed such that the sealing material is filled in the portions with no gap.
1. A liquid crystal display panel arranging a sealing material between a lower substrate and an upper substrate, and holding a liquid crystal layer between the lower substrate and the upper substrate, wherein the upper substrate has one-side surface thereof formed in a recessed shape as viewed from above, a flexible printed circuit board is connected to a region of the lower substrate where the upper substrate and the lower substrate do not overlap with each other, the sealing material is formed along a shape of the upper substrate that includes the recessed shape, and a width of the sealing material at a first portion that is formed along the recessed shape is wider than a width of a second portion of the sealing material that is not formed along the recessed shape.
2. A liquid crystal display panel according to claim 1 , wherein the upper substrate is formed of a plastic substrate or a glass substrate.
3. A liquid crystal display panel according to claim 1 , wherein portions where the lower substrate and the upper substrate overlap with each other and correspond to both sides of the portion where the flexible printed circuit board is arranged are formed such that the sealing material is filled in the portions with no gap.
4. A liquid crystal display panel according to claim 1 , wherein a driver chip for controlling driving of the liquid crystal display panel is arranged on the lower substrate where the lower substrate and the upper substrate do not overlap with each other.
5. A liquid crystal display panel according to claim 4 , wherein the flexible printed circuit board and the driver chip are arranged parallel to a side surface of the lower substrate.
6. A liquid crystal display panel according to claim 4 , wherein the flexible printed circuit board and the driver chip are arranged in parallel to each other and parallel to a side of the lower substrate.
