摘要： A display substrate. The display substrate is provided with multiple subpixels (P) arranged in an array, and comprises a driving circuit substrate (110), multiple first electrodes (130), a pixel definition layer (140), and a light-emitting material layer (150). The driving circuit substrate (110) comprises multiple pixel driving circuits (120) and a protective insulating layer (112); the protective insulating layer (112) comprises multiple first via holes (112A) exposing output ends (121) of the multiple pixel driving circuits (120); and the multiple first electrodes (130) are electrically connected to the output ends (121) of the multiple pixel driving circuits (120) by means of the multiple first via holes (112A), respectively. The pixel definition layer (140) is at least disposed on the side of each of the multiple first electrodes (130) away from the driving circuit substrate (110), and comprises multiple subpixel openings (141) that respectively expose the multiple first electrodes (130) and at least one partition structure (142) that is provided on the pixel definition layer (140). The light-emitting layer (150) is disposed on the side of the pixel definition layer (140) away from the driving circuit substrate (110) and is at least located in the multiple subpixel openings (141). The pixel definition layer (140) comprises a fist pixel definition sublayer (1401) and a second pixel definition sublayer (1402); and the width of the second pixel definition sublayer (1402) is greater than that of the first pixel definition sublayer (1401). In the display substrate, the problem of lateral electrical crosstalk between adjacent subpixels (P) does not occur, thereby achieving a good display effect.

摘要： A display substrate, a display panel and a display device are disclosed. The display substrate includes: a base substrate (1), and a color film structure (2) and a transparent conductive oxide film layer (3) subsequently laminated on the base substrate (1). The color film structure (2) includes a plurality of color filter units arranged in a matrix and having different colors; at least one color of the color filter units in the color film structure (2) includes at least two layers of laminated color filter films, refractive indices of the color filter films gradually increase in a direction from the base substrate (1) towards the transparent conductive oxide film layer (3), and one layer of the color filter films adjacent to the base substrate (1) has refractive index larger than that of the base substrate (1), one layer of the color filter films adjacent to the transparent conductive oxide film layer (3) has refractive index less than that of the transparent conductive oxide film layer (3). The display substrate reduces the loss of light transmitted in the display panel, and thus the display brightness of the display device is increased.
