  • Patent number: 11774654
    Abstract: A substrate, a mask, a display panel and a display device are provided. The substrate includes a base substrate and a color resistance layer on the base substrate. The substrate has a display area and a non-display area. The color resistance layer in the non-display area includes a weakening unit for weakening or disconnecting connection between the color resistance layer in the non-display area away from the display area and the color resistance layer in the display area. During the development and washing process of the substrate, even if the color resistance layer in the non-display area is peeled off, the color resistance layer in the display area will not be peeled off together, which helps to ensure the safety and reliability of the color resistance layer in the display area.

  • Patent number: 11275277
    Abstract: The disclosure provides a color filter substrate, including a base substrate and a black matrix in multiple rows and multiple columns arranged on the base substrate; a color filter layer on the base substrate, including a plurality of color channels arranged at intervals and defined by the multiple columns of the black matrix, and each color channel including a plurality of color units defined by the multiple rows of the black matrix; and at least one spacer reference structure, each including at least two sub-structures respectively arranged in at least two adjacent color channels and on a same row of the black matrix, each sub-structure being arranged on a surface of the black matrix distal to the base substrate; a height difference between surfaces of the at least two sub-structures distal to the base substrate is less than a first threshold.

  • Patent number: 11175442
    Abstract: The present disclosure provides a color filter substrate and a display panel. The color filter substrate is divided into a display region and a non-display region around the display region, and includes a base and a color filter layer on the base. The color filter layer includes a plurality of columns of color resists arranged at intervals, any two adjacent columns of color resists in the display region define one of a plurality of first openings, any two adjacent color resists in the non-display region define one of a plurality of second openings, and a width of an orthographic projection of the second opening on the base is greater than a width of an orthographic projection of the first opening on the base.

  • Patent number: 10948761
    Abstract: The present disclosure provides a color filter substrate including: a base substrate; and a filter layer on the base substrate and including a plurality of color resist units of a plurality of colors. Orthographic projections of adjacent color resist units of different colors on the base substrate have an overlapping region. Therefore, the color filter substrate has at least one of the following advantages: the structure is simple; the production cost is reduced; the aperture ratio of the display device including the color filter substrate is improved; and the defect caused by static electricity is solved.

  • Publication number: 20200278579
    Abstract: Embodiments of the present disclosure provide a color filter substrate, a manufacturing method thereof, and a display device. The color filter substrate includes a substrate, color blocks, and light shielding portions positioned on the substrate. The color blocks and the light shielding portions are alternately arranged along a first direction. A size of the light shielding portions along the first direction depends on a sensitivity of human eyes to a mixture of colors, which are different, of the color blocks on both sides of each of the light shielding portions.
