摘要： The present disclosure provides a light-emitting layer, an organic light emitting diode (OLED) device, and a display apparatus. The light-emitting layer has a host material containing a first photocrosslinker group. A guest material containing a second photocrosslinker group is prepared. The host material and the guest material are mixed in a solvent to form a mixture. The mixture is coated, annealed, and UV-irradiated on a substrate to form the light-emitting layer. As such, the disclosed light-emitting layer is prepared by the polymerization after being on the substrate. The light-emitting layer has a mesh structure. The mesh structure improves energy transfer between the host material and guest material and increases the lifespan of the resultant OLED device and OLED display apparatus.

摘要： The present disclosure relates to the technical field of liquid crystal display. A liquid crystal panel and a display panel are provided. A main post spacer of the liquid crystal panel is arranged on a first substrate. A stopping structure used to stop the main post spacer from moving in a direction away from a second substrate is arranged on the second substrate. Hence, even if lots of liquid crystals are filled, the main post spacer and the second substrate may be kept in a seamless state due to the stopping structure.
