Abstract
Image quality degradation in a display device with two liquid crystal cells is reduced. For this purpose, as an image signal for a liquid crystal display panel in which a display image is generated by light passing through a rear liquid crystal cell and a front liquid crystal cell, an image processing unit generates a rear image signal for the rear liquid crystal cell and a rear image signal for the front liquid crystal cell. This image processing unit includes a gradation value conversion unit that performs a gradation value conversion on an input image signal so as to generate a rear image signal for the rear liquid crystal cell, and a limit processing unit that performs a process of limiting a value of the rear image signal output from the gradation value conversion unit to a predetermined limit value.
