Benefits of technology

[0028]The invention increases a distance between a display area and a sealant at a corner to reduce the risk of the sealant at the corner overflowing to the display area, thereby reduces the risk of light leakage from the display panel.

Problems solved by technology

Once the position and width of the sealant fluctuate during a process, the sealant may overflow into the display area, causing light leakage.
However, the distance between the display area and the sealant at the corner is closer, and the risk of an overflow of the sealant is more likely to occur.

Abstract

The invention discloses a display panel and a display device. The display panel includes a first substrate and a sealant disposed on the first substrate. The first substrate includes a display area and a bezel area surrounding the display area. The sealant is disposed in the bezel area and surrounds the display area, wherein a widened portion is disposed between the display area and the sealant at a corner to increase a shortest distance between a boundary of the display area and the sealant at the corner.
