PROBLEM TO BE SOLVED: To able common driving pattern to be outputted in good order for every selected line number by giving arrangement information to a chip with respect to a simultaneously selected line number by which 128 is in divisible, e.g. in three line simultaneous selection with 128 line output, etc. SOLUTION: Signals to driver control circuits are switched based on chip arrangement information by incorporating 128 driver control circuit which are controlled by the output of a shift register consisting of a 44-stage flip-flop. Besides a timing of output of data being transferred within the shift register to the outside of the chip is changed based on the chip arrangement information. Thereby, a shift deviation is prevented at the time of simultaneous selection of three lines by multi-line driving method of 128-line output. In addition, a deviation between common output and pulse signals for starting scanning at cascade connection is prevented. Since the simultaneous selection of three lines is possible when 128 lines are outputted, new generation of expenses for development can be prevented and the cost can be reduced.
