The display device of an embodiment of the present invention includes a display section which includes a pixel having a plurality of sub pixels and displays an image whose luminance is based on a luminance gradation of an inputted display signal, wherein the display section is arranged so that an integral value obtained by carrying out the following steps (a) to (d) is not more than 0.0202, the step (a) of measuring surface luminance of the display section and oblique luminance of the display section viewed at 60° from a front direction of the display section, the step (b) of standardizing the front luminance and the oblique luminance so as to calculate front standardized brightness x and oblique standardized brightness, the step (c) of determining n of x^(n/2.2) so that an integral value of a difference between x^(n/2.2) and the front standardized brightness x is equal to an integral value of a difference between the oblique standardized brightness and the front standardized brightness x, the step (d) of integrating an absolute value of a difference between x^(n/2.2) and the oblique standardized brightness, from minimum luminance to maximum luminance of the front standardized brightness x, so as to obtain an integral value.
