    Abstract: The present invention provides a display panel and a method for manufacturing the same. The method comprises steps of forming a black matrix and forming a sealant, wherein the black matrix layer contains a thermochromic material at the position corresponding to the sealant, so that when the sealant is cured with ultraviolet light, the thermochromic material layer is transparent. In such case, a side of the first substrate away from the sealant can be irradiated and ultraviolet light passes through the first substrate and the thermochromic material to cure the sealant, thus achieving a uniform irradiation of ultraviolet light and a high curing efficiency. After the sealant is cured, the thermochromic material can become black by changing the temperature thereof so as to avoid the light leakage.

  • Patent number: 10634966
    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.
