Abstract
In a lateral electric field liquid crystal display device, a major electrode portion for generating a lateral electric field is formed using a layer different from a layer on which other electrodes and lines are formed. In this case, the major portion is formed to have a thickness of {fraction (1/20)} to ⅓ of the thickness of each of the other electrodes and lines. Thus, flatness of a base film of an alignment layer is significantly improved, also alignment layer material can be coated and formed with high flatness on the base film, and rubbing of the alignment layer material can be performed uniformly for the overall substrate surface.
