The present invention relates to a display panel, a manufacturing method thereof, and a display device, wherein the display panel includes a pixel definition layer, an isolation column, an organic light-emitting unit and a cathode. The pixel definition layer defines a plurality of pixel definition openings; the isolation columns are located in the spaced regions between the plurality of pixel definition openings; the organic light-emitting unit is formed in the corresponding pixel definition openings; the cathode is covered on the pixel definition layer without the isolation columns. At least part of the area is covered with the organic light-emitting unit. When the above-mentioned display device and the display panel are impacted, the isolation column is subjected to force first. Since there is no cathode on the isolation column, the cathode will not be damaged when the isolation column is damaged, which avoids the isolation column becoming a stress point and causing organic damage when external force acts. The problem of peeling off the light-emitting unit and the cathode improves the bending resistance and the drop impact strength of the display panel, thereby improving the display performance and service life of the display panel. |
