Abstract

A display device includes a display area and a periphery area. The display device includes a display panel and a touch module located on the display panel. The display panel includes a driving substrate, a display medium layer located on the driving substrate, a top electrode located on the display medium layer, and a sealant surrounding the display medium layer and the top electrode. The sealant includes a first section and at least one second section connected with the first section. The first section is located between the top electrode and the driving substrate. A thickness of the second section is greater than a thickness of the first section. The touch module includes a bonding region located in the periphery region. An orthogonal projection of the bonding region on the driving substrate overlaps an orthogonal projection of the first section on the driving substrate.
