Crystal display apparatus and method of controlling the same

A liquid crystal display apparatus comprising:

• a liquid crystal modulation element which includes a liquid crystal layer between a first electrode and a second electrode and modulates light from a light source;
• a controller which controls a potential difference to be applied between the first and second electrodes such that the difference of a potential of the second electrode relative to a potential of the first electrode alternates periodically between positive and negative;
• and
• a memory which stores controlling information on the potential difference between the first and second electrodes for suppressing flicker within a certain range,
• wherein the liquid crystal display apparatus operates in a first mode and a second mode, the first mode and the second mode being different in the amount of light entering the liquid crystal modulation element from the light source,
• the memory has first information associated with the first mode and second information associated with the second mode stored therein as the controlling information, and
• the controller controls the potential difference between the first and second electrodes based on the first information when the first mode is set and controls the potential difference between the first and second electrodes based on the second information when the second mode is set.
