Abstract
A display panel includes a first electrode, a first hole transport layer, a light-emitting layer, and a second electrode which are sequentially stacked on a substrate in a first direction. The light-emitting layer includes a first light-emitting region, a second light-emitting region and a third light-emitting region, which are arranged in a second direction and emit different colors of light. The first hole transport layer includes a first hole transport region opposite to the first light-emitting region and the second light-emitting region, and a second hole transport region opposite to the third light-emitting region. The first hole transport region of the first hole transport layer is formed of a hole matrix and a first p-type doping material.
Claims20
A display panel, comprising a first electrode, a first hole transport layer, a light-emitting layer, and a second electrode which are sequentially stacked on a substrate in a first direction, wherein the first direction is a direction pointing to the second electrode from the first electrode, and a second direction is perpendicular to the first direction;
- wherein the light-emitting layer comprises a first light-emitting region, a second light-emitting region and a third light-emitting region, which are arranged in the second direction and emit different colors of light;
