Abstract

A display device includes a display panel, a data driving part and a gate driving part. The display panel includes a first pixel row. The first pixel row includes a first pixel connected to an (n+1)-th gate line and an (m+1)-th data line (where ‘n’ and ‘m’ are natural numbers), and a second pixel connected to an n-th gate line and an (m+2)-th data line. The data driving part applies a data voltage having a first polarity with respect to a reference voltage to the (m+1)-th data line, and applies a data voltage having a second polarity with respect to the reference voltage to the (m+2)-th data line. The gate driving part sequentially applies a gate signal to the n-th gate line and the (n+1)-th gate line.
