Abstract
The present disclosure provides a display panel, including a metal light shielding layer having a first spacing area, an electrode layer having a second spacing area, and an insulating layer having a recessed area. The second spacing area is disposed offset from the first spacing area; and an insulating layer is disposed between the metal light shielding layer and the electrode layer. An orthographic projection of the recessed area on the metal light shielding layer is at least partially located between a first boundary and a second boundary. The first boundary is an orthographic projection of a sidewall of the first spacing area away from the second spacing area on the metal light shielding layer, and the second boundary is an orthographic projection of a sidewall of the second spacing area away from the first spacing area on the metal light shielding layer.
