Liquid crystal display device and fabrication method thereof

A liquid crystal display device including a first substrate and a second substrate which are arranged to face each other via a liquid crystal layer, the first substrate and the second substrate each being formed of a resin base material, comprising:

• a first adhesive layer which is formed on the liquid crystal layer side of the first substrate to fix a liquid crystal drive layer formed with pixels in a matrix to the first substrate;
• a second adhesive layer which is formed on the liquid crystal layer side of the second substrate to fix a color filter layer formed with a light shielding film and a colored filter layer both corresponding to each of the pixels to the second substrate;
• and
• an under layer which is formed on the liquid crystal layer side of the color filter layer and formed of a thin film layer having a thermal expansion coefficient smaller than that of the second substrate.

A method for fabricating a liquid crystal display device including a first substrate and a second substrate which are arranged to face each other via a liquid crystal layer, the first substrate and the second substrate each being formed of a resin base material, the method comprising:

• forming a light shielding film and a colored filter layer both corresponding to a pixel and a protective film above a first base material having a heat resistance greater than that of the resin base material;
• forming a protective base material which supports and protects the light shielding film, the colored filter layer, and the protective film on an upper surface side of the first base material;
• removing the first base material chemically and/or mechanically;
• fixing the light shielding film, the colored filter layer, and the protective film from which the first base material is removed to the first substrate via an adhesive layer;
• and
• removing the protective base material from above the light shielding film, the colored filter layer, and the protective film which are fixed to the first substrate.
