A display panel and a display device are disclosed. The display panel includes a first electrode layer, a light-emitting layer, and a second electrode layer sequentially stacked. The light-emitting layer includes first pixels disposed in a display light-transmitting region and second pixels disposed in a main display region. A first opening between the first pixels adjacent to each other is defined by the second electrode layer. A thickness of the light-emitting layer corresponding to the first opening is less than a thickness of the light-emitting layer between the second pixels adjacent to each other. Not only can the light transmittance of the display light-transmitting region be increased, but the process can be simpler.

Display panel and display device with reduced thickness of light-emitting layer in display light-transmitting region

Provided is a display panel, comprising a flexible substrate, a transition layer, a buffer layer, a drive layer, a functional layer, and a thin-film encapsulation layer. The transition layer covers one side of the flexible substrate; the buffer layer covers one side, away from a rigid carrier, of the transition layer; the drive layer covers one side, away from the transition layer, of the buffer layer; the functional layer covers one side, away from the buffer layer, of the drive layer; and the thin-film encapsulation layer covers the surface of the functional layer. According to the invention, a sulfydryl-containing transition layer is modified on a flexible substrate by means of sulfydryl modification to realize tight adhesion between the flexible substrate and a buffer layer in a drive layer, so that the adhesion force between the flexible substrate and the buffer layer is greatly enhanced by means of chemical adsorption.

Display panel and manufacturing method thereof

A display panel and manufacturing method thereof are provided. The display panel includes a substrate, a first electrode, a hole injection layer, a hole transport layer, an electron blocking layer, an organic electroluminescent layer, a hole blocking layer, an electron transport layer, an electron injection layer, and a second electrode arranged sequentially. The electron blocking layer corresponding to a red sub-pixel region of the organic electroluminescent layer is made of a p-type red light host material. Accordingly, the present invention effectively simplifies a manufacturing process, adjusts and balances charge carriers, and improves device performance.

A display panel and a display device are provided. The display panel includes a substrate layer and a light-emitting layer. The substrate layer includes a first shielding layer corresponding to a first display area. The light-emitting layer comprises first light-emitting pixels arranged in the first display area and second light-emitting pixels arranged in a second display area. The first shielding layer includes: a first shielding sub-part corresponding to the first light-emitting pixel and a second shielding sub-part connecting two adjacent first shielding sub-parts.
