Title (EN) COLOR FILTER STRUCTURE AND METHOD OF MAKING
(FR) STRUCTURE DE FILTRE COULEURS ET PROCEDE DE FABRICATION
Abstract: front page image
(EN)An improved planar color filter structure (140) to reduce defects in the display devices incorporating the color filter structures, including active matrix displays. A color filter substrate (102) has a thicker polyamide black matrix (132) formed thereon and a transparent polyamide layer (142) formed over the black matrix. The transparent layer is exposed through the black matrix and developed to remove the unexposed portions over the black matrix. The resulting surface (146) is substantially planar and facilitates the forming of the remaining layers to form a substantially planar color filter structure.
(FR)La présente invention concerne une structure (40) de filtre couleurs plane améliorée, permettant d'atténuer des défauts dans les dispositifs d'affichage incorporant lesdites structures de filtre couleurs, y compris les affichages à matrice active. Un substrat (102) de filtre couleurs comporte une matrice noire (132) de polyamide, plus épaisse, disposée sur ledit substrat et une couche transparente (142) de polyamide disposée sur la matrice noire. La couche transparente est exposée à travers la matrice noire et développée de manière à retirer les parties non exposées recouvrant la matrice noire. La surface résultante (146) est sensiblement plane et favorise la formation des couches restantes permettant, ainsi, de former une structure de filtre couleurs sensiblement plane.
