Abstract

The organic black matrix material, formulated by a photosensitive acrylic resin and color pigments, has superb optical performance with a specular reflection of 0.36% at 30 degree(s) incident angle. Its optical density, with help from a metallic layer, has been achieved at 5.5. Since this organic material is a negative photoresist, the fabrication process is rather simple. Using such a black matrix, a high- resolution 2.4' X 2.4' full-color (alpha) -Si TFT LCD with 480 X 480 dots has been successfully fabricated. In combination of a wide-view retardation film, this AMLCD unit is suitable for high-performance display applications.
