A display device includes a display pixel unit and a signal processing unit. The display pixel unit includes a plurality of pixels arranged in a horizontal direction and a vertical direction. The signal processing unit determines a correction value corresponding to a target pixel based on differences between gradation data of the target pixel and gradation data of peripheral pixels disposed in the horizontal direction, the vertical direction, and an oblique direction with respect to the target pixel, respectively, among the plurality of pixels, increases or decreases a pixel value of the target pixel based on the correction value, and corrects the gradation data of the target pixel to reduce the differences. 1. A display device comprising:a display pixel unit in which a plurality of pixels are arranged in a horizontal direction and a vertical direction; anda signal processing unit configured to determine a correction value corresponding to a target pixel based on differences between gradation data of the target pixel and gradation data of peripheral pixels disposed in the horizontal direction, the vertical direction, and an oblique direction with respect to the target pixel, respectively, among the plurality of pixels, to increase or decrease a pixel value of the target pixel based on the correction value, and to correct the gradation data of the target pixel to reduce the differences.2. The display device according to claim 1 , whereinthe signal processing unit calculates the differences between the gradation data of the target pixel and the gradation data of the peripheral pixels disposed in the horizontal direction, the vertical direction, and the oblique direction with respect to the target pixel, respectively, specifies the maximum value from the calculation results, and sets the maximum value to the correction value.3. The display device according to claim 1 , whereinthe signal processing unit calculates the differences based on correction coefficients ...
