  • Patent number: 12113076
    Abstract: Embodiments of the disclosure provide a display substrate and a method for manufacturing the same. The display substrate includes: a base substrate; a thin film transistor including a source-drain metal layer and a first insulating layer; a second insulating layer; a color resist layer; and a third insulating layer. The third insulating layer comprises a first via hole that sequentially penetrates the third insulating layer, the color resist layer and the second insulating layer and thus extends from the third insulating layer to the source-drain metal layer. A sidewall of the first via hole comprises a first portion formed of a material of the second insulating layer, a second portion formed of a material of the color resist layer, and a third portion formed of a material of the third insulating layer, the second portion is between the first portion and the third portion.

  • Publication number: 20240272502
    Abstract: Provided are an array substrate and a manufacturing method therefor, a display panel, and a display device. The array substrate includes: a plurality of electrodes arranged in an array. The electrode includes a plurality of strip electrodes that are connected to each other and spaced. The plurality of strip electrodes at least have two thicknesses. A distance between two adjacent strip electrodes is less than a preset value. During manufacturing, a mask used for forming each layer of sub-electrodes includes a plurality of strip-shaped shading regions that are connected to each other and spaced in a first direction. Strip-shaped shading regions in a mask used for sub-electrodes formed subsequently are integrally shifted by a first distance in the first direction relative to strip-shaped shading regions in a mask used for sub-electrodes formed last time.
