Title
(EN) COLOR FILTER SUBSTRATE, METHOD FOR MANUFACTURING THE SAME AND DISPLAY DEVICE
Abstract
(EN)

The present disclosure discloses a color filter substrate, a manufacture method thereof and a display device. The color filter substrate includes a substrate; and a light channel layer on a side of the substrate. The light channel layer includes a first photonic crystal layer and a second photonic crystal layer stacked with each other up and down. The light channel layer includes a plurality of light channel units formed by a periodic arrangement of three different primary-color light channel units. Each of the light channel units includes a photonic crystal block of the first photonic crystal layer and a photonic crystal block of the second photonic crystal layer with an orthographic projection of the photonic crystal block of the first photonic crystal layer on the substrate overlapping an orthographic projection of the photonic crystal block of the second photonic crystal layer on the substrate.
