Abstract:
1. A display device comprising: a data line corresponding to each column of pixels arranged in a matrix, wherein a data signal for each pixel is supplied to the pixel through the data line, and an amplifier circuit comprising wherein the amplifier circuit supplies the data signal to the data line after stabilizing the data signal, the input signal is an analog output obtained by charging a plurality of capacitors in accordance with a value of each bit of a digital signal and averaging charged voltages of the plurality of capacitors, wherein each of the plurality of capacitors has a capacitance weighted corresponding to each bit of the digital signal of a plurality of bits, the output signal is supplied to a data line having a predetermined capacitance, an average of charged voltages of the plurality of capacitors is obtained by connecting one terminal of each of the plurality of capacitors in parallel using a connection switch, and the switch is switched ON after a predetermined time has elapsed after the connection switch is switched ON.
