DISPLAY SUBSTRATE AND MANUFACTURING METHOD THEREOF, AND DISPLAY DEVICE

摘要

The present invention provides a display substrate and a manufacturing method thereof, and a display device, the display substrate comprises an active area, a first black matrix and a light leaking region, the first black matrix surrounding the active area, and the light leaking region surrounding the periphery of the first black matrix, wherein the display substrate further comprises a filter layer surrounding the first black matrix, the filter layer covers the light leaking region so as to reduce the transmittance of light at the light leaking region, and the resistivity of the filter layer is larger than that of the first black matrix. In the display substrate, the light leaking region is covered by the filter layer, the transmittance of light at light leaking region is thus reduced, therefore, likelihood of viewer observing light leakage at the light leaking region may be decreased.
