Abstract
A display substrate is disclosed, comprising a display area and a peripheral area surrounding the display area. The display substrate is fixed to a counter substrate in the peripheral area by a frame sealant. The display substrate comprises a substrate and a curing energy transmissive layer. A projection of the frame sealant on the substrate falls within or coincides with that of the curing energy transmissive layer. Since the curing energy transmissive layer transparent for the curing energy beam is provided in the display substrate, the frame sealant can be irradiated from the display substrate side through the curing energy transmissive layer, instead of from the counter substrate side. This improves the efficiency for curing the frame sealant. A display panel, a method for fabricating the display substrate and the display panel, and a display device are disclosed.
