Abstract
A gate line drive circuit includes: X level shift circuits configured to convert first address signals into second address signals; and a logic circuit configured to drive a selection gate line of N gate lines of a display unit based on the second address signals by supplying a first driving voltage to the selection gate line and by supplying a second driving voltage to non-selection gate lines of the N gate lines other than the selection gate line. X is an integer of 1 or more. N is equal to 2 raised to a power X. The first address signals includes X voltages each of which is a first voltage or a second voltage. The second address signals includes X driving voltages each of which is the first driving voltage or the second driving voltage.
