Abstract
A mother substrate for display substrates, a manufacture method thereof, a display substrate and a display device are provided. The mother substrate for display substrates includes multiple display element formation regions and a dividing line surrounding each display element formation region. A recess-protrusion structure is provided between the dividing line and the display element formation region, the recess-protrusion structure includes multiple recesses and protrusions which are arranged alternately, and extension directions of the recess and the protrusion are identical to an extension direction of the dividing line.
Claims20
A display substrate, comprising a display element formation region and a recess-protrusion structure surrounding the display element formation region, wherein the recess-protrusion structure comprises a plurality of recesses and protrusions which are arranged alternately;
- wherein the recesses and the protrusions are made of a same material;
- wherein a width of a protrusion located in a middle region of the recess-protrusion structure is greater than a width of each protrusion located in a marginal region of the recess-protrusion structure.
A mother substrate for display substrates, comprising a plurality of display element formation regions and a dividing line surrounding each of the plurality of display element formation regions;
- wherein a recess-protrusion structure is provided between the dividing line and the display element formation region, the recess-protrusion structure comprises a plurality of recesses and protrusions which are arranged alternately, and extension directions of the protrusion and the recess are identical to an extension direction of the dividing line;
- wherein the recesses and the protrusions are made of a same material;
- wherein a width of a protrusion located in a middle region of the recess-protrusion structure is greater than a width of each protrusion located in a marginal region of the recess-protrusion structure.
A method for manufacturing a mother substrate for display substrates, the mother substrate for display substrates comprising a plurality of display element formation regions and a dividing line surrounding each of the plurality of display element formation regions, wherein the method comprises:
- forming a material layer at least at a region between the dividing line and the display element formation region, and patterning the material layer to form a recess-protrusion structure, wherein the recess-protrusion structure comprises a plurality of recesses and protrusions which are arranged alternately, and extension directions of the protrusion and the recess are identical to an extension direction of the dividing line;
- wherein the recesses and the protrusions are made of a same material;
- wherein a width of a protrusion located in a middle region of the recess-protrusion structure is greater than a width of each protrusion located in a marginal region of the recess-protrusion structure.
