Abstract

Provided is a display panel, including: a base substrate, a display structure, a black matrix pattern, and a cylindrical lens structure layer. The black matrix pattern includes a plurality of first openings. The display panel is provided with a plurality of sub-pixel regions arranged in rows and columns. The first openings are disposed in the sub-pixel regions. The cylindrical lens structure layer includes a plurality of strip-shaped cylindrical lens structure and has a plurality of focal lines in an orthographic projection on the black matrix pattern. The focal lines are parallel to the length direction of the cylindrical lens structures. The focal lines partition each sub-pixel region into a plurality of regions. One of the plurality of regions is a non-crosstalk region. The black matrix pattern further includes second openings in the non-crosstalk regions. The second openings are disposed outside regions where the first openings are disposed.
