題があった。However, if an organic film such as a color filter layer or its intermediate film or protective film is present at the interface of the substrate that the sealant comes into contact with, the organic film absorbs moisture, which shortens the life of the liquid crystal through the organic film, or Poor adhesion between the membrane and sealant reduced the mechanical strength of the panel itself. Furthermore, when UV-curable resin is used as a sealant,
There were problems such as absorption of ultraviolet rays by the organic film, which caused the sealant to not be sufficiently cured and react with the liquid crystal, or adversely affect alignment.
本発明は、このような課題を解決するもので、その目的

れた。In this example as described above, the color filter layer is formed excluding the part that comes in contact with the sealant, and the sealant is brought into direct contact with the common electrode, so that the spacer does not dig into the color filter layer, and the liquid crystal Cell gap hunting has become easier. In addition, the color filter layer no longer absorbs ultraviolet rays, making it possible to cure the ultraviolet curable sealant in a short time, thereby preventing the sealant from being uncured. Furthermore, the adhesion of the sealant has also been improved, greatly improving reliability.
