Display panel and display device
By setting a light-shielding structure in the second display area of the display panel, the light emission angle of the sub-pixels is limited, which solves the problem of color leakage when the display panel does not need full-area privacy protection from the side viewing angle, and achieves a partial privacy protection effect, thus improving confidentiality.

AI Technical Summary
Technical Problem
Existing display panels, when not requiring full-surface privacy protection, have a higher likelihood of data leakage due to consistent color when viewed from the side.
Method used
A first light-shielding structure is set in the second display area of the display panel, so that the colors displayed are different when viewed from the front and from the side. By setting the light-shielding structure in the light-emitting direction of the sub-pixels in the second display area, the light-emitting angle is limited to achieve a local privacy protection effect.
Benefits of technology
The display panel exhibits color differences from side and front viewing angles, enhancing security and preventing unauthorized access to input information.
