Abstract
Official abstract text for this publication.
A source AMP output circuit ( 10 ) is provided with a switching circuit ( 17 ) for carrying out the following operation. That is, in a case where a polarity is reversed, the switching circuit ( 17 ) disconnects a data signal line (S(M)) from output terminals of a positive amplifier circuit ( 15 ) and a negative polarity amplifier circuit ( 16 ) each included in the source AMP output circuit ( 10 ), and then connects the data signal line S(M) to a power supply which is in a power supply voltage range (Vdd 1 to Vdd 3 ) of the positive polarity amplifier circuit ( 15 ) or to a power supply which is in a power supply voltage range (Vdd 2 to Vdd 4 ) of the negative polarity amplifier circuit ( 16 ).
