## Abstract

A display device includes a display panel, a middle frame, an annular retaining edge and a cover module. One side of the middle frame is provided with the annular retaining edge around a through hole, a receiving space communicating with the through hole is enclosed by the annular retaining edge and the middle frame, and the display panel is limited in the receiving space; and the cover module includes a protective cover covering a side, with the annular retaining edge, of the middle frame, a first buffer is placed between the protective cover and the display panel, and the protective cover fixes the display panel in the receiving space in a pressing manner through the first buffer. The protective cover fixes the display panel in a first groove in a pressing manner through the first buffer.

## Claims

### Claim 1

A display device, comprising:
a display panel;
a middle frame, the display panel mounted on a side face of the middle frame;
an annular retaining edge, arranged on the side face, for mounting the display panel of the middle frame, an inner peripheral wall of the annular retaining edge and an inner peripheral wall of the middle frame spaced from each other, a receiving space enclosed by the annular retaining edge and the middle frame, and the display panel limited and mounted in the receiving space; and
a cover module comprising a protective cover covering a side, with the annular retaining edge of the middle frame, a first buffer placed between the protective cover and the display panel, and the protective cover fixing the display panel in the receiving space in a pressing manner through the first buffer;
wherein there is no gap between the display panel and the first buffer;
wherein the protective cover and the annular retaining edge are not contact directly, there is a gap between the protective cover and the annular retaining edge, and a size of the gap is smaller than a thickness of the display panel;
wherein the first buffer is buffer foam arranged along a circumferential edge of the display panel.

### Claim 2 (depends on 1)

The display device of claim 1, wherein a second buffer is arranged between the middle frame and the display panel, and a third buffer is arranged between the annular retaining edge and the display panel.

### Claim 3 (depends on 1)
