<p>PROBLEM TO BE SOLVED: To obtain a liquid crystal display device which allows driving with a low voltage and has excellent display characteristics. SOLUTION: Comb-shaped pixel electrodes 11 and common electrodes 12 are arranged on a substrate 13 and a counter substrate 14 in such a manner that the teeth of respective combs are paralleled and alternated with each other. When voltage is impressed on the liquid crystal display device, an electric field in a diagonal direction is generated by the pixel electrodes 11 and the common electrodes 12 and liquid crystal molecules 10b having positive dielectric anisotropy are oriented along the electric field in a diagonal direction. The pixel electrodes 11 and the common electrodes 12 are preferably arranged by parting the spacings therebetween in such a manner that the electric field in a diagonal direction is made more nearly horizontal in order to eliminate the dependence of the liquid crystal molecules 10b on visual field angles. On the other hand, a higher driving voltage is made necessary in order to make the inter-electrode spacing larger. Then, the angle A formed by the electric field direction with the substrate surface with respect to the liquid crystal display device having a cell gap of 4 to 10μm is set larger than 20 deg. and below 45 deg..</p> |
