Display panel, method for manufacturing same, and display device

A display panel, comprising:

• a first substrate and a second substrate arranged in a cell, wherein the display panel has a display area and a peripheral area located at a periphery of the display area, and the display area comprises a plurality of sub-pixels arranged in an array;
• the first substrate comprises a first base substrate, and a black matrix and a spacer arranged on the first base substrate, and the second substrate comprises a second base substrate and a conductive layer arranged on the second base substrate;
• the black matrix defines a plurality of opening patterns corresponding to the plurality of sub-pixels, and the spacer comprises a display area spacer located in the display area and a peripheral area spacer located in the peripheral area;
• the peripheral area comprises a first region and a second region, the number of conductive layers of the second substrate in the first region is less than the number of conductive layers in the second region, and the peripheral area spacer comprises a plurality of first peripheral area spacers provided in the first region;
• the first peripheral area spacer is located on a side of the black matrix facing away from the first base substrate, an insulating island is provided between the first peripheral area spacer and the black matrix, a pattern of the insulating island comprises a plurality of island patterns arranged at intervals to be isolated from each other, and each of the island patterns is correspondingly arranged between at least one of the first peripheral area spacers and the black matrix and coincides with an orthographic projection of the corresponding first peripheral area spacer on the first base substrate.
