By reducing the thickness of the light shielding film in the notch area, good light transmittance of the notch area is kept, and a light transmissive effect made by cutting the notch area off in the existing technology is achieved, thus the notch area does not need to be cut off, which solves the technical problem that the notch area needs to be cut off in the existing display panels and reduces the manufacturing cost of the display panels.

The present disclosure is described below in conjunction with a plurality of cross section diagrams of a selected position in FIG. 2.

A light shielding mold frame 33 is disposed between the notch area 2 and the display area 1, and the light shielding mold frame 33 connects with the array substrate 31 and the color filter 32.

In one embodiment, the light shielding mold frame 33 is a light shielding mold frame of thermoplastic-optical clear film (ODF) to avoid liquid crystal in the display area spillover into the notch area.

In one embodiment, the display panel also comprises a photoresist layer fitted to the light shielding mold frame 33. For example, a bottom bezel or left bezel or right bezel of the notch area is blocked by a black matrix (BM) to avoid light leakage from the display area to the notch area.
