The present disclosure is directed to a light-shielding colored resin layer formed on a substrate, and a patterned protective layer formed on the colored resin layer. By removing the colored resin layer exposed in an opening of the protective layer by dry etching, thereby patterning the colored resin layer, a partition wall in which the protective layer is provided on a patterned colored resin layer is formed. This partition wall partitions the display surface of an image display device into a plurality of regions; and an image display device is formed by filling spaces, which are partitioned by the partition wall, with a color developing material.

Provided is a light-emitting element to highly efficiently emit light in different colors. The light-emitting element includes: a cathode; an anode; a light-emitting layer formed between the cathode and the anode, and including a plurality of light-emitting regions respectively emitting light of different wavelengths; and an electron-transport layer formed between the cathode and the light-emitting layer, and including a plurality of regions each corresponding to one of the light-emitting regions. The electron-transport layer includes a Zn.sub.1-XMg.sub.XO film (where X is 0≤X<1).
