Abstract

A liquid crystal display device can suppress pixel-based gradation fluctuations observed upon change in angle of view with increased size as it meets wide angle of view characteristics required of a large-sized liquid crystal display device. A device in which a liquid crystal material is sealed between a pair of substrates 31, 32, a plurality of pixel electrodes 38 for applying voltage across the liquid crystal material is arranged on the substrate 31, a common electrode 12 for applying a voltage common to the pixel electrodes 38 is arranged on the substrate 32, and in which a gate line 22 and a drain line 23 of a switching element adapted to control the voltage applied across the pixel electrodes 38 are provided for extending substantially at right angles to each other. In the device, orientation of the liquid crystal molecules 18 neighboring to the pixel electrode 38 is perpendicular to that of liquid crystal molecules 19 neighboring to the common electrode 12, while the respective orientations are substantially parallel to the direction of the gate line 22 or that of the drain line 23.
