Abstract: Pixel electrodes adjacent to each other along a first axis are supplied with pixel potentials having opposite polarities with respect to a potential of a common electrode. The pixel electrode includes straight parts. Electric fields between the straight parts and the common electrode are applied to negative type liquid crystal material. An electric field between the straight parts of the adjacent pixel electrodes is applied to the negative type liquid crystal material. An opposite substrate includes a second region opposed to a first region between the straight parts of the adjacent pixel electrodes. At least a part of visible light transmitted through the first region is transmitted through the second region. Angles of the straight parts with respect to an axis perpendicular to direction of initial alignment of the liquid crystal material have a size of not less than 15° and not more than 30°.

The display panel includes: a light-shielding layer including imaging apertures, a light-emitting element layer including first light-emitting elements and second light-emitting elements, a touch functional layer, and a fingerprint recognition module. The orthographic projection of the second light-emitting element on the light-shielding layer is closer to the corresponding imaging aperture than the orthographic projection of the first light-emitting element on the light-shielding layer. In a first detection stage, the first light-emitting elements emit light, the second light-emitting elements do not emit light, and the fingerprint recognition module generates a first fingerprint image. In a second detection stage, the second light-emitting elements emit light, and the fingerprint recognition module generates a second fingerprint image. The first fingerprint image and the second fingerprint image are combined into a fingerprint image.
