Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 202510904983.X filed July 01, 2025, the disclosure of which is incorporated herein by reference in its entirety. TECHNICAL FIELD Embodiments of the present disclosure relate to the field of display technologies and, in particular, to a display panel and a display device. BACKGROUND At present, display technology has penetrated into all aspects of people's daily life. To keep pace with this trend, more and more materials and technologies are used in display screens, thereby bringing great convenience to people's daily life and work. The display of micro light-emitting diodes (micro-LEDs) is considered to be the next generation display technology due to characteristics such as ultra-high brightness, a high resolution, a high contrast ratio, fast response time, low power consumption, high transparency and a miniaturized size. In the related art, thanks to the miniaturization of the size of the micro-LED chip, micro-LED transparent display screens can achieve a larger proportion of an area of a transparent region and higher transparency so that the transparent display of the micro-LEDs has a wide range of application scenarios such as the transparent display in front of the driver's seat of the vehicle and the projection display of the front windshield of the vehicle. However, since the micro-LED transparent display screen has a relatively divergent light pattern of light emission, the wide-angle beams are easily reflected by objects such as the front windshield and side window glass of the vehicle and enter the human eyes to form a reflection and generate a virtual image, which interferes with the driver's observation of the scene outside the vehicle and affects driving safety. SUMMARY Embodiments of the present disclosure provide a display panel and a display device. A light-shielding layer with openings is disposed at a light emission side of light-emitting elements. The light-shielding layer can effectively adjust an angle of light emitted from the light-emitting element to meet different requirements for light emission. In a first aspect, the embodiments of the present disclosure provide a display panel. The display panel includes an array substrate, a light-shielding layer and multiple light-emitting elements. The multiple light-emitting elements are disposed on the array substrate, and the light-shielding layer is located on one side of the multiple light-emitting elements facing away from the array substrate. The light-shielding layer includes multiple openings. In a thickness direction of the display panel, the multiple openings at least partially overlap the multiple light-emitting elements in one-to-one correspondence, and a center of a light-emitting element among the multiple light-emitting elements overlaps a respective one of the multiple openings and does not overlap the light-shielding layer. In a second aspect, the embodiments of the present disclosure further provide a display device. The display device includes any display panel described in the first aspect.
