IMAGE DISPLAY ELEMENT AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2022159882
Kind Code:
A
Abstract:
To reduce light crosstalk and improve light extraction efficiency.SOLUTION: An image display element (1) has: a substrate (11); a plurality of light-emitting elements (12) that emit excitation light, being placed on the substrate; a plurality of color conversion layers (13a and 13b) that convert at least a part of the excitation light into light having a different wavelength from the excitation light, being placed on opposite surfaces to the substrate of the plurality of light-emitting elements; and a reflection film (16) that covers at least a part of lateral faces of the plurality of color conversion layers and the opposite surfaces to the substrate of the plurality of light-emitting elements, between the plurality of adjacent color conversion layers.SELECTED DRAWING: Figure 1(a)
