A display device, comprising:
- a display panel, comprising a display region and a peripheral region around the display region;
- and
- an optical module, disposed on a light-exiting side of the display panel, the optical module configured to shift light emitted from the display panel towards edges of the display panel so as to make a part of the light shift into the peripheral region and emit from the peripheral region,
- the optical module comprises a refracting layer, wherein a set angle is provided between a light incident surface of each of the refracting layers and a light-exiting surface of the display panel and each of the refracting layers is used to shift the light towards the edges of the display panel by a set distance,
- the set distance h satisfies the formula:
