Abstract

A display structure is provided. The display structure includes a substrate, a dam, a first film layer, a second film layer, and a third film layer. The third film layer has a first spread rate for the first film layer, the third film layer has a second spread rate for the second film layer, and the first spread rate is less than the second spread rate. The spread rates of the third film layer on the first and second film layers are different, so as to slow the spread rate of the third film layer near an area of the dam, thereby reducing the risk that the third film layer overflows the dam, so that the encapsulation reliability of the display structure can be improved.
