ABSTRACT:
A transmissive color filter layer is disposed over a transparent substrate such as glass in a transparent display area, and a reflective color filter layer is formed in a reflective display area. An overcoat layer is formed on the transmissive color filter layer and the reflective color filter layer so as to cover both of them. The overcoat layer has a multigap structure having a first layer thickness on the transmissive color filter layer and a second layer thickness on the reflective color filter layer, which is thicker than the first layer thickness. In the substrate for this liquid crystal panel, the overcoat layer is also disposed in the transparent display area. Therefore, the adhesion of the transparent electrode can be enhanced, and the transmissive color filter layer can be protected.
