Abstract
The present invention provides a liquid crystal display device having a high display quality. The liquid crystal display device displays an image by applying a voltage by a first electrode and a second electrode across a liquid crystal layer which takes a vertical alignment in the absence of an applied voltage. The first electrode includes a lower conductive layer, a dielectric layer covering at least a portion of the lower conductive layer, and an upper conductive layer provided on one side of the dielectric layer which is closer to the liquid crystal layer. The upper conductive layer includes a first opening, and the lower conductive layer is provided so as to oppose at least a portion of the first opening via the dielectric layer.
