Zusammenfassung:	A display device having a visual angle control film can attenuate an interference phenomenon between a panel and a visual angle control film and effectively shield unnecessary light of a visual angle. The display device comprises a display panel; and a visual angle control film disposed on the display panel, wherein the visual angle control film may include a plurality of light-shielding patterns for shielding light advancing in a side direction except a front direction of the display panel in a visual angle control mode, and each of the plurality of light-shielding patterns may have a thickness in the range of 8% to 25% of a pixel size of the display panel, an interval in the range of 33% to 39% of the pixel area, and a slope angle in the range of ±5° to 15° based on 90°.
