It should be noted that the display layer 10 may be a light emitting layer in a display screen, or the display layer 10 may also be a thin film transistor layer including a light emitting layer and a thin film transistor for driving the light emitting layer to emit light to display an image. The display screen is a special-shaped display screen, and the display area 12 of the display layer 10 comprises a special-shaped edge display area 121. The shape of the shaped edge display area 121 may be, for example, an arc shape, a diamond shape, or the like. As shown in fig. 1, the special-shaped display screen may be a screen with a bang-bang type non-display area 11, and is used for arranging a camera, a flash lamp, and the like. The display area 12 includes a shaped edge display area 121 that interfaces with the bang type non-display area 11 and a shaped edge 122 that is curved as shown in fig. 1.
In the embodiment of the present invention, the light shielding layer may be disposed on the display surface side of the display layer 10, or may be disposed on another substrate independent from the display layer 10, so as to cover the display layer 10. As shown in fig. 5, a first substrate 20 is disposed on one side of the display layer 10, and the light-shielding layer is disposed on the first substrate 20.

Alternatively, the projection area of the light shielding region 21 on the pixel unit 13 at the shaped edge gradually decreases from the side near the non-display region 11 to the side near the display region 12. Referring to fig. 3, the pixel unit 13 is a regular rectangle, and the boundary edge between the light-shielding region 21 and the light-transmitting region 22 extends along the shape of the irregular edge; for example, the boundary edge between the light-shielding region 21 and the light-transmitting region 22 is arc-shaped, and the light-shielding region 21 covers at least a part of the pixel units 13 at the special-shaped edge, so that the light-shielding area of the light-shielding region 21 on the pixel units 13 at the special-shaped edge is gradually reduced in the direction in which the non-display region 11 approaches the display region 12, and further the luminance of the pixel units 13 in the special-shaped edge display region 121 is gradually increased in the direction in which the non-display region 11 approaches the display region 12, until the pixel units 13 are not covered by the light-shielding region 21, the pixel units 13 exhibit 100% luminance. Therefore, the display effect at the special-shaped edge of the special-shaped display screen is further ensured, and the problem of zigzag display at the special-shaped edge of the display area 12 is prevented.
