    Abstract: A display apparatus includes a liquid crystal display element, a backlight, and a plurality of circuits conducting the following. A drive signal for driving the backlight is formed according to an adjustment value calculated from the one-screen average image luminance in the image signal for display and a predetermined linear luminance adjustment curve. An image signal amplification control is then conducted according to a linear image luminance correction curve specified by the adjustment value, the average luminance, and one or both of the one-screen minimum and maximum luminance values detected from the image signal. The corrected image is then supplied to the liquid crystal display element. In so doing, reduced power consumption is realized in the backlight of a liquid crystal display element while maintaining the image quality of displayed images.
