Abstract: 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 area of the display panel, an interval in the range of 33% to 39% of the pixel size, and a slope angle in the range of ±5° to 15° based on 90°.

Abstract: The disclosure relates to a display device and a method for driving the same, which are capable of enhancing grayscale expression capability at low luminance. An image processor of the display device according to an embodiment of the disclosure converts data of a low-grayscale area lower than a threshold value into low-grayscale reproduction data, using a grayscale reproduction mask pattern including a selected value, the threshold value and a detailed adjustment value, thereby reproducing a luminance of the low-grayscale area through a combination of the threshold value, the selected value and the detailed adjustment value.
