Abstract
(EN)
A color filter substrate, a manufacturing method therefor, and a display device. The color filter substrate comprises: a substrate (1) and a light channel layer (2) disposed at one side of the substrate (1). The light channel layer (2) comprises a first photonic crystal layer and a second photonic crystal layer stacked one on the other; the light channel layer (2) comprises multiple light channel units (5, 6, 7), said light channel units (5, 6, 7) being of three different types having three primary colors and arranged in patterns; each light channel unit (5, 6, 7) comprises a photonic crystal block (R, B) of the first photonic crystal layer and a corresponding photonic crystal block (G, R) of the second photonic crystal layer, the orthographic projections of said blocks on the substrate (1) overlapping one another; the photonic band gap of the photonic crystal block (R, B) of the first photonic crystal layer is different from the photonic band gap of the corresponding photonic crystal block (G, R) of the second photonic crystal layer, such that only light of one of the three primary colors is allowed to pass through while light of the other two primary colors is blocked.

Substrat de filtre de couleur, son procédé de fabrication, et dispositif d’affichage. Le substrat de filtre de couleur comprend un substrat (1) et une couche de chemin lumineux (2) disposée sur un côté du substrat (1). La couche de chemin lumineux (2) comprend une première couche de cristal photonique et une seconde couche de cristal photonique empilées l'une sur l'autre; la couche de chemin lumineux (2) comprend de multiples unités de chemin lumineux (5, 6, 7), lesdites unités de chemin lumineux (5, 6, 7) étant de trois types différents ayant trois couleurs primaires et disposées en motifs; chaque unité de canal de lumière (5, 6, 7) comprend un bloc de cristal photonique (R, B) de la première couche de cristal photonique et un bloc de cristal photonique correspondant (G, R) de la seconde couche de cristal photonique, les projections orthographiques desdits blocs sur le substrat (1) se chevauchant mutuellement; l'espace de bande interdite photonique du bloc de cristal photonique (R, B) de la première couche de cristal photonique est différent de l'espace de bande interdite photonique du bloc de cristal photonique correspondant (G, R) de la seconde couche de cristal photonique, de telle sorte que seule la lumière d'une des trois couleurs primaires peut passer à travers tandis que la lumière des deux autres couleurs primaires est bloquée.
