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.
