Abstract
The display apparatus includes: N differential amplifiers having output ends, amplifying N input voltages and outputting amplified voltages, and a resistor ladder having N voltage supply points connected to the output ends of the N differential amplifiers and M voltage output points outputting M level voltages. The M voltage output points are connected to capacitive loads on input sides of the amplifiers, and at least one N differential amplifier has an input pair and an output end connected to one of the N voltage supply point. One of the N input voltages is received by one of the input pair, the other one of the input pair is connected to one of the M voltage output points outputting a level voltage closest to a voltage at the one voltage supply point. The one voltage supply point and the one voltage output point are at different positions on the resistor ladder.
