    摘要: A display substrate, a display panel and a manufacturing method thereof, and a display device are disclosed. The display substrate includes: a first substrate; a pixel defining layer on the first substrate and having pixel openings; and light emitting devices in one-to-one correspondence with the pixel openings. The light emitting device includes a first electrode and a light emitting function layer, the first electrode is between the pixel defining layer and the first substrate, and includes a main body portion exposed by the pixel opening; the light emitting function layer is in the pixel opening and on a side of the main body portion away from the first substrate, at least a part of the light emitting function layer directly faces the main body portion, and the part of the light emitting function layer directly facing the main body portion is a curved film layer protruding towards the first substrate.

    摘要: A light-emitting substrate includes; a base, an isolation portion disposed on the base and located in an isolation region located outside a light-emitting region, and a second insulating pattern located in the light-emitting region. The isolation portion includes a first conductive pattern, a second conductive pattern and a first insulating pattern that are sequentially stacked on the base; an orthogonal projection of the first conductive pattern on the base is located within an orthogonal projection of the second conductive pattern on the base; and a side face of the first conductive pattern proximate to the light-emitting region and a corresponding side face of the second conductive pattern proximate to the light-emitting region have a first gap therebetween. A side face of the second insulating pattern proximate to the first insulating pattern and a side face of the first insulating pattern proximate to the second insulating pattern have a second gap therebetween.

    摘要: The present disclosure provides a pixel unit including a plurality of sub-pixels of different colors. Each sub-pixel includes a first transflective layer, a wavelength selective cavity, and a second transflective layer disposed successively along an incident light direction. A height of the wavelength selective cavity of each sub-pixel in the incident light direction is designed so as to select light having a wavelength corresponding to a color of the sub-pixel from light which is incident through the first transflective layer and reflected between the first transflective layer and the second transflective layer, and selected light exits through the second transflective layer. The present disclosure further provides a display substrate and a display panel.

    摘要: A display backplane, a manufacturing method thereof, and a display device are provided. The display backplane includes a base substrate. A thin film transistor array layer, a protective layer, a planarization layer, and a light-emitting element are arranged on the base substrate. A first through hole is formed in the protective layer, and a second through hole is formed in the planarization layer. The first through hole and the second through hole are connected. A source electrode or a drain electrode is electrically connected to an anode via the first through hole and the second through hole. Each of the first through hole and the second through hole has a sidewall inclined relative to the base substrate.
