<p>PROBLEM TO BE SOLVED: To provide a matrix type image display device in which the difference in the input signal levels from an external circuit such as a control circuit and an image signal processing circuit and the actual driving signal levels of respective pixels is absorbed, an additional constitution such as an interface circuit is not required and the cost and power consumption are reduced. SOLUTION: 0 V/5 V sampling pulses outputted from logic circuits LOGj are respective shifted to 10 V for a high potential side and -8 V for a low potential side by connected two stage level shifters LS1j and LS2j . At that time, one of driving voltages (5 V) of a data signal line driving circuit SD is fixed and the other driving voltage (0 V) of the circuit SD and the driving voltage of a scanning signal line driving circuit GD are shifted.</p> |
