Abstract
A display device in which gradation wiring lines of positive polarity included in a (m)th group of wiring lines of positive polarity and gradation wiring lines of positive polarity included in a (m+1)th group of wiring lines of positive polarity are alternately provided, and in which gradation wiring lines of negative polarity included in a (m′)th group of wiring lines of negative polarity and gradation wiring lines of negative polarity included in a (m′+1)th group of wiring lines of negative polarity are alternately provided. The device further includes (n)th resistance dividing circuits of positive polarity which include (m)th resistance dividing circuits connected to the (m)th group of wiring lines of positive polarity, and (m+1)th resistance dividing circuits connected to the (m+1)th group of wiring lines of positive polarity. Resistance dividing circuits of negative polarity are connected in a similar manner to the gradation wiring lines of negative polarity.
