1. A display device, comprising:
a display panel having a display region and a peripheral region surrounding the display region, the display panel comprising: an array substrate, an opposite substrate and a liquid crystal layer, wherein the array substrate and the opposite substrate are opposite to each other, the liquid crystal layer is between the array substrate and the opposite substrate, a light shielding layer is on a side of the array substrate close to the liquid crystal layer, and an orthographic projection of the light shielding layer on the array substrate is located in the peripheral region; and
a light source configured to emit light to a lateral side of the display panel, the light being incident into the liquid crystal layer from the lateral side of the display panel;
the light shielding layer is a reflective layer;
the light source is on a lateral side of the opposite substrate, which is on a light outing side of the display device, to emit light towards the lateral side of the opposite substrate; and
the light shielding layer is directly arranged on the array substrate in the peripheral region, to reflect a part of the light emitted from the light source, irradiated onto the light shielding layer, back to the opposite substrate so as to improve light extraction efficiency of the opposite substrate during displaying of the display panel.
