| titleOfInvention | A mask, a display substrate, a manufacturing method thereof, and a display device |
| abstract | The present invention provides a mask plate, a display substrate, a method for making the same, and a display device. The mask plate, used for manufacturing a columnar spacer on a display substrate, includes a light-shielding layer, and the light-shielding layer includes a light-shielding pattern and a For the plurality of opening patterns surrounded by the shading pattern, in the direction perpendicular to the mask plane, the cross-section of the opening patterns is an inverted trapezoid, and the inverted trapezoid is not a right-angled trapezoid. When the spacer is made by using the mask of the embodiment of the present invention, it can block and absorb the ultraviolet rays of the parallel half-angle on both sides of the opening pattern, so that the difference between the top size and the bottom size of the spacer is reduced, so that the spacer can be placed in the spacer. Under the condition that the size of the bottom of the spacer remains unchanged, the size of the top of the prepared spacer is increased, and the supporting force of the prepared spacer is improved, so that the Mura defect can be effectively avoided. |
