Display apparatus and method for manufacturing same

A method for manufacturing a display apparatus, comprising following steps:

• providing a display device, wherein the display device comprises a plurality of pixel points arranged in an array, and the pixel points emit a first-color light;
• forming a barrier layer above the pixel points, with the first-color light passing through the barrier layer;
• forming a grid layer above the pixel points, wherein the barrier layer is positioned between the pixel points and the grid layer, the grid layer comprises a plurality of grid holes arranged in an array, the grid holes are arranged relative to the pixel points, a bottom portion of the grid holes exposes the barrier layer, and the first-color light is emitted through the grid holes;
• forming a reflective layer on the grid layer, wherein the reflective layer at least covers a sidewall of the grid holes while exposing the pixel points;
• and
• forming a wavelength conversion layer above the grid layer, wherein the wavelength conversion layer comprises a plurality of first wavelength conversion units, which fill in at least part of the grid holes and convert the first-color light into a second-color light.
