Abstract
The present application provides a display panel, a manufacturing method thereof, and a display device; first intervals and second intervals are defined between a plurality of first electrodes, a plurality of first pixel banks are arranged corresponding to the first intervals, and a plurality of second pixel banks are arranged corresponding to the second intervals, wherein the second pixel banks cross over the first pixel banks, and a thickness of the second pixel banks is greater than a thickness of the first pixel banks, so that light-emitting materials of a same color can be continuously printed between adjacent ones of the second pixel banks.
Claims20
A display panel, wherein a pixel definition layer of the display panel comprises:
- a plurality of first pixel banks arranged along a first direction;
- and
- a plurality of second pixel banks arranged along a second direction, wherein adjacent ones of the first pixel banks and adjacent ones of the second pixel banks surround to define one of light-exiting areas;
- and an included angle is formed between the first direction and the second direction,
- wherein, in the second direction, light-emitting materials in the light-exiting areas are same, and a thickness of the second pixel banks is greater than a thickness of the first pixel banks.
A method of manufacturing a display panel, comprising:
- providing an array substrate and forming a plurality of first electrodes arranged in an array on the array substrate, wherein each of first intervals is formed between adjacent ones of the first electrodes in a first direction, and each of second intervals is formed between adjacent ones of the first electrodes in a second direction;
- forming first pixel banks in the first intervals, wherein a thickness of the first pixel banks is greater than a thickness of the first electrodes;
- forming second pixel banks in the second intervals to form a pixel definition layer, wherein a thickness of the second pixel banks is greater than the thickness of the first pixel banks, and the second pixel banks cover portions of the first pixel banks and portions of the first electrodes, so that each of printing grooves is formed between adjacent ones of the second pixel banks;
- continuously printing light-emitting materials of a same color in a same one of the printing grooves, and printing light-emitting materials of different colors in different ones of the printing grooves to form a light-emitting layer, wherein the light-emitting layer is formed on the first electrodes which are not covered by the second pixel banks;
- and
- depositing second electrodes on the light-emitting layer.
A display device comprising a display panel, a pixel definition layer of the display panel comprising:
- a plurality of first pixel banks arranged along a first direction;
- and
- a plurality of second pixel banks arranged along a second direction, wherein adjacent ones of the first pixel banks and adjacent ones of the second pixel banks surround to define one of light-exiting areas;
- and an included angle is formed between the first direction and the second direction,
- wherein, in the second direction, light-emitting materials in the light-exiting areas are same, and a thickness of the second pixel banks is greater than a thickness of the first pixel banks.
