Abstract
Official abstract text for this publication.
A liquid crystal display device according to the invention has an effect that burn-in and a flicker do not occur. Dummy pixels are provided around pixels of the liquid crystal display device. A first voltage higher in order than a reference voltage and a second voltage lower in order than the first voltage are applied to a pixel electrode of a liquid crystal device included in the dummy pixel while being temporally shifted. The liquid crystal display device changes, on the basis of an electric current flowing to a second opposed electrode when the first voltage is applied and an electric current flowing to the second opposed electrode when the second voltage is applied, a ratio of effective voltages of a positive voltage and a negative voltage applied to a liquid crystal device included in the pixel that displays an image.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid crystal display device comprising: a display pixel in which liquid crystal is held between a first electrode and a common electrode; a driving circuit that temporally alternately applies, to the first electrode, a first voltage further on a high-order side than a predetermined reference voltage and corresponding to gradation of the display pixel and a second voltage further on a low-order side than the predetermined reference voltage and correspon…
