Abstract
An anode includes at least one first electrode, and a reflecting electrode disposed on a side of the at least one first electrode configured to face a light emitting portion of the light emitting device.
Claims15
A display substrate, comprising:
- a base substrate;
- and
- a plurality of sub-pixels disposed on the base substrate, each sub-pixel including a light emitting device;
- wherein
- the light emitting device includes an anode, a cathode and a light emitting portion disposed between the anode and the cathode;
- the anode of the light emitting device is closer to the base substrate than the cathode of the light emitting device;
- the anode includes at least one first electrode and a reflecting electrode disposed on a side of the at least one first electrode configured to face a light emitting portion of the light emitting device;
- the reflecting electrode in the anode is configured to reflect light emitted by the light emitting portion;
- the cathode is configured to be light-transmittable;
- the plurality of sub-pixels include at least two types of sub-pixels, and each type of sub-pixels is configured to display a color;
- a distance between the reflecting electrode and the light emitting portion in each sub-pixel for displaying one color is different from a distance between the reflecting electrode and the light emitting portion in each sub-pixel for displaying another color;
- the at least two types of sub-pixels include:
- a red sub-pixel, a green sub-pixel, and a blue sub-pixel;
- a distance between the reflecting electrode and the light emitting portion in the blue sub-pixel is less than a distance between the reflecting electrode and the light emitting portion in the green sub-pixel;
- a distance between the reflecting electrode and the light emitting portion in the green sub-pixel is less than a distance between the reflecting electrode and the light emitting portion in the red sub-pixel.

A method of manufacturing a display substrate, comprising:
- providing a base substrate;
- forming a plurality of anodes on a side of the base substrate;
- and
- forming a plurality of light emitting portions on sides of the plurality of anodes away from the base substrate, respectively;
- wherein
- forming the plurality of anodes on the side of the base substrate, includes:
