摘要： A display panel and a display device are provided. The display panel includes a first color sub-pixels and a second color sub-pixel. The first color sub-pixel includes a first effective light emitting region, the second color sub-pixel includes a second effective light emitting region. The first color sub-pixel includes a first color light emitting layer, the second color sub-pixel includes a second color light emitting layer, for one second effective light emitting region, along the length direction, a difference between the maximum size of the second color light emitting layer and the maximum size of the second effective light emitting region is a first difference, and along the width direction, a difference between the maximum size of the second color light emitting layer and the maximum size of the second effective light emitting region is a second difference, and the first difference is less than the second difference.

摘要： A display panel and a display device are provided. The display panel includes a first color sub-pixels and a second color sub-pixel. The first color sub-pixel includes a first effective light emitting region, the second color sub-pixel includes a second effective light emitting region, an area of the second effective light emitting region is smaller than that of the first effective light emitting region. The first color sub-pixel includes a first color light emitting layer, the second color sub-pixel includes a second color light emitting layer, an area ratio between orthographic projections of the first color light emitting layer and the first effective light emitting region on the base substrate is less than an area ratio between orthographic projections of the second color light emitting layer and the second effective light emitting region on the base substrate.
