Abstract: Disclosed is a mask for curing of a sealant, and the mask comprises a support plate. The support plate has a flat structure, which includes a first plane and a second plane. The first plane is provided with a shielding layer thereon. When the mask is used, it is placed in parallel with a liquid crystal panel coated with the sealant to be cured, and light for curing the sealant transmits through the mask and irradiates the liquid display panel. The support plate is transparent, and the shielding layer allows part of light to transmit through. Under a condition that a frame of a display panel becomes narrower, the mask for curing of the sealant according to the present disclosure can have a good performance, and thus incomplete curing of the sealant and decomposition of liquid crystal can be avoided.

Abstract: The technical field of display device is related to. A display screen is disclosed. The display screen includes an integrated circuit board and an organic insulating film. A power signal line is arranged on the integrated circuit board. The organic insulating film is provided with a plurality of grooves with an equal distance thereamong, and a cathode is arranged on the organic insulating film. The cathode is buried in a groove and contacts the power signal line, or an anode is arranged on the cathode, is buried in the groove, and contacts the power signal line. The organic insulating film near an interface between the anode and the cathode is flat, and a disconnection would not occur to the cathode that is formed under the anode. Therefore, a signal of the integrated circuit board can be transmitted to the cathode in the active area, and display defect of the panel will not be resulted in. A width of the anode is reduced, and the anode is buried in the groove. That is, the anode is disconnected from an edge of the organic insulating film. In this manner, the case in the prior art, i.e., the organic insulating film near the interface between the anode and the cathode becomes non-flat after developing of an organic barrier layer, and an under cut is formed at an edge of the anode, which leads to disconnection of the cathode, can be avoided.
