Title: LIQUID CRYSTAL DISPLAY DEVICE
Abstract:
Provided is a liquid crystal display device wherein flickering is unlikely to occur when displaying single colors, even when data voltage polarity is inverted for each frame. The liquid crystal display device comprises an active matrix substrate and a counter substrate. The active matrix substrate comprises: a plurality of pixels having pixel electrodes 16 arranged in a matrix; and a plurality of source lines SL having applied thereto data voltage exhibiting either positive polarity or negative polarity. The counter substrate comprises color filters of a plurality of colors. Two source lines (SLn, SLn+1/SLn+2, SLn+3) are provided for each of three columns of pixels L1, L2 . The polarity of the data voltage applied to the source lines is inverted at each frame. The plurality of pixels include, for each color: a pixel having a pixel electrode 16 connected to a source line having applied thereto data voltage having a positive polarity; and a pixel having a pixel electrode 16 connected to a source line having applied thereto data voltage having a negative polarity.
