1. A display device, comprising a display panel, a sensor disposed at a first side of the display panel, and a polarizer disposed between the sensor and the display panel, wherein ambient light enters the sensor through the display panel and the polarizer, and
wherein a polarization direction of light emitted from the display device to the sensor comprises, at least, a first polarization direction, and the first polarization direction is parallel to an absorption axis of the polarizer, wherein the polarizer comprises an arc surface, a convex surface of the arc surface faces away from the sensor,
wherein the display panel comprises a first polarizing layer disposed on a side of the display panel close to the sensor, a second polarizing layer disposed on a side of the display panel away from the sensor, a liquid crystal layer disposed between the first polarizing layer and the second polarizing layer, and a third polarizing layer disposed between the first polarizing layer and the polarizer,
wherein an absorption axis of the first polarizing layer is perpendicular to an absorption axis of the second polarizing layer, and the absorption axis of the polarizer is parallel to the absorption axis of the first polarizing layer,
wherein the display device comprises a first via hole, the first via hole only penetrates through the third polarizing layer,
wherein an orthographic projection of the first via hole on the sensor is located within the sensor.
