Abstract
A liquid crystal display element includes: a first substrate having a first surface and including a pixel electrode; a second substrate having a second surface opposing to the first surface, and including a light-shielding film, a thickness adjusting film and a counter electrode arranged in sequence in a direction to the second surface; a sealing material having a frame-shape to bond the first substrate and the second substrate; a liquid crystal layer provided in a region surrounded by the sealing material and between the first substrate and the second substrate, wherein the thickness adjusting film is provided to cover the light-shielding film to define the thickness of the liquid crystal layer, and has a contact hole, wherein the counter electrode is provided to oppose to the pixel electrode, and electrically connected to the light shielding film via the contact hole.
