Patent ID: 8243105

Claim:
A display device, comprising: a display section which includes a pixel having a first sub pixel and a second sub pixel and displays an image whose luminance is based on a luminance gradation of an inputted display signal; and a control section which causes luminance of the first sub pixel and luminance of the second sub pixel to be different from each other and generates a first display signal serving as a display signal in a first sub frame and a second display signal serving as a display signal in a second sub frame so that division of a frame does not change total luminance outputted from the display section in a single frame, so as to output the first and second display signal to the display section, wherein the display section is arranged so that a first integral value obtained by carrying out 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 an angle of 60° with respect to 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 the first integral value, wherein the control section adjusts a ratio of sub frames, obtained by dividing the frame, so as to adjust the first integral value.
