DISPLAY DEVICE, DISPLACE DEVICE ADJUSTMENT METHOD, IMAGE DISPLAY MONITOR, AND TELEVISION RECEIVER

摘要

A display device includes a pixel consisting of a plurality of sub-pixels. A display unit (14) displays an image of luminance based on the luminance gradation of an inputted display signal. The display unit (14) performs the following: (a) measures a surface luminance of the display unit and oblique luminance at the angle of 60 degrees from the front side; (b) normalizes the front luminance and the oblique luminance so as to obtain the front normalized lightness x and the oblique normalized lightness; and (c) decides n in x^(n/2.2) so that integrated value of the difference between x^(n/2.2) and the front normalized lightness x is identical to the integrated value of the difference between the oblique normalized lightness and the front normalized lightness x; wherein (d) an integrated value obtained by integrating the absolute value of the difference between the x^(n/2.2) and the oblique normalized lightness over the minimum luminance to the maximum luminance of the front normalized lightness x is not greater than 0.0202.
