Abstract
A display device includes: a display panel; and a polarizer, an optical adhesive, and a cover plate sequentially arranged on the display panel. The display panel has a transparent region. The polarizer has first and second surfaces parallel to each other, and the first surface is proximal to the display panel. The polarizer has therein a through hole penetrating through the first and second surfaces. The through hole has first and second boundaries at the first and second surfaces, respectively. An orthogonal projection of the first boundary on the second surface is inside and not in contact with the second boundary. For third and fourth boundaries of the through hole parallel to the first boundary, an orthogonal projection of the third boundary on the fourth boundary does not extend beyond the fourth boundary, the third boundary being closer to the first boundary than the fourth boundary.
