Abstract

A LCD device of display panels includes n-bit (n<m) driving first display panel that displays first image based on m-bit input image data, n-bit driving second display panel that displays second image based on the m-bit input image data, and image processor including first gradation converter that converts gradation of the m-bit input image data into n-bit gradation, second gradation converter that converts gradation of the m-bit input image data into m1-bit (m1≥m) gradation, and extension processor that performs extension processing of extending gradation expression with the n bits on the input image data converted into the m1-bit gradation. The n-bit driving first display panel displays the first image based on the n-bit input image data, and the n-bit driving second display panel displays the second image based on the n-bit input image data subjected to the extension processing.
