Display apparatus improving light effriciency and preventing color mixture

A display device comprising:

• a plurality of pixels disposed on a substrate, wherein each pixel includes a first subpixel, a second subpixel adjacent to the first subpixel, and a third subpixel adjacent to the second subpixel, the second subpixel disposed between the first subpixel and the third subpixel;
• a first color filter disposed in the first subpixel, and configured to emit light having a first color;
• a second color filter disposed in the second subpixel, and configured to emit light having a second color;
• and
• a third color filter disposed in the third subpixel, and configured to emit light having a third color,
• wherein an upper surface of the second color filter is disposed a greater distance from the substrate than an upper surface of the first color filter,
• wherein the first subpixel further includes a first light path changing layer disposed on the first color filter and contacting a first side surface of the second color filter, and
• wherein the second subpixel does not include a light path changing layer.
