  • Patent number: 10488712
    Abstract: Provided is a liquid crystal display apparatus such that a liquid material for an alignment film can be prevented from entering a region for forming a sealing member so that the peeling of the sealing member caused by the deterioration of adhesion between the sealing member and a substrate can be prevented and a narrow frame can be attained. A display panel includes a rectangular-shaped TFT substrate and CF substrate bonded together with a sealing member formed at a periphery thereof, a liquid crystal layer provided at a region surrounded by the sealing member between the two substrates to form a display region, and an groove and protrusion part provided between the display region and the sealing member having a groove formed along a circumferential direction in a region between the display region and the sealing member, the groove and protrusion part having wave-like shape in a plan view.

  • Patent number: 10234712
    Abstract: A method produces a liquid crystal display. The display includes a plurality of pixels having sub-pixels that include one opening and one color layer. Some of the sub-pixels having the same color are continuously spaced in one direction. In the method, overlapping photolithographic patterns produce mask openings in which a color layer in two spaced adjacent sub-pixels is to be formed. The mask openings each have a size corresponding to two or more adjacent sub-pixels; and the number of sub-pixels of the same color that are continuously arranged in the one direction is at least twice the total number of sub-pixels of the same color included in each of the pixels.
