Abstract: The present application discloses a splicing screen and a display device, which relates to a technical field of display. In technical solutions provided by the present application, structures of a first unit panel and a second unit panel that are mutually spliced in the splicing screen are improved. A first light-emitting device layer defining a display area AA thereof in the first unit panel overlaps a non-display area of the second unit panel for displaying, so as to visually eliminate or weaken visual influence of the non-display area on the splicing screen, lift restriction of the non-display area NA on spacing between adjacent pixel units of different unit panels in the splicing screen, and improve visual senses of the splicing screen.

Abstract: A liquid crystal display panel and a display device are provided. A first metal line is disposed on a first substrate of the liquid crystal display panel. An orthographic projection of the first metal line on a pixel electrode covers a first trunk electrode. A voltage difference V1 between the first metal line and a common electrode is small, so that a liquid crystal molecule corresponding to the first metal line does not deflect. In this way, a problem of an insufficient liquid crystal recovery force when the liquid crystal display panel is pressed is resolved, eliminating poor liquid crystal diffusion as a result of pressing and resulting in improving display quality.

Abstract: Provided is a display panel comprising an anode layer, a sacrificial layer disposed on an anode layer, a pixel definition layer covering the sacrificial layer and the anode layer, and a light-emitting functional layer disposed in the groove and the light-emitting area opening, and a manufacturing method thereof, wherein the sacrificial layer is formed with a groove at a position corresponding to the light-emitting area opening. In this way, the sacrificial layer forming at the light-emitting area opening can be removed to form a groove at the same time in the process of forming the light-emitting area opening by exposure and development, so that it is possible to ensure that no pixel definition layer remains on the anode layer at the light-emitting area opening, thereby solving the problem that the light-emitting functional layer cannot be spread.

Abstract: A spliced screen and a display device are disclosed. The spliced screen includes: a spliced unit screen, wherein the spliced unit screen includes a plurality of unit screens, and a splicing gap is defined between the unit screens adjacent to each other; a light-emitting diode (LED) strip light, wherein the LED strip light is disposed on the splicing gap; and a light-emitting cover plate, wherein the light-emitting cover plate is disposed above the spliced unit screen. By disposing the light-transmitting cover plate, the splicing gap between the unit screens adjacent to each other can be eliminated by the LED strip light without forming an uneven display surface of the spliced screen. Therefore, an entire visual effect of the spliced screen is improved.
