Patent number: 11803073Abstract: A display substrate has first and second conductive layers separated from one another by an insulation layer. The first and second conductive layers are used to integrally form on the display substrate, pixel units in a relatively central display area of the substrate and integrated gate driving circuitry as well as associated wirings thereof in one or more peripheral areas. The first and second conductive layers are covered by a first protection layer made of a first electrically insulative material. A second and supplementing protection layer is provided on top of the first protection layer. The supplementing protection layer (buffer layer) is formed of a material different from that of the first protection layer so as to provide supplemental resistance against corrosive chemical agents and supplemental resistance against formation of cracks.Type: GrantFiled: June 6, 2022Date of Patent: October 31, 2023Assignee: Samsung Display Co., Ltd.Inventors: Kook-Hyun Choi, Hyo-Taek Lim, Dong-Ho Shin, Young-Je Cho, Yong-Jo Kim, Sang-Yong No, Sung-Hoon Kim, Hyo-Seop Kim

Patent number: 8619218Abstract: A display substrate and a display device including the same are provided. The display substrate includes a first substrate which is divided into a display portion including pixel regions and a non-display portion including a region other than the display portion. Color filters are formed in the pixel regions of the substrate to respective thicknesses. At least one stepped pattern is formed on the non-display portion of the substrate and from the same material as used to form at least one of the color filters. The stepped patterns are formed at an area occupancy density of 20% or more of the non-display portion. A minimum distance is maintained between the stepped patterns and the pixel regions.Type: GrantFiled: March 10, 2011Date of Patent: December 31, 2013Assignee: Samsung Display Co., Ltd.Inventors: Hyuk-Jin Kim, Hyo-Taek Lim, Kweon-Sam Hong, Hyun Park, Tae-Hyeong Kim
