Abstract:
A method of manufacturing a full-color organic electro-luminescent device, comprising the steps of:patterning an indium-tin-oxide glass substrate; cleaning the indium-tin-oxide glass substrate; forming an insulation pad over the indium-tin-oxide glass substrate; forming a low shadow mask over the insulation pad by a first dry film photo-resist process; forming a high shadow mask over the insulation pad by conducting a second dry film photo-resist process; forming a hole-transport layer over the indium-tin-oxide glass substrate by conducting a vapor-depositing process; conducting three vapor-depositing processes simultaneously to form red, green and blue light-emitting materials on the hole-transport layer in the same step using the low shadow mask and the high shadow mask as a barrier; forming an electron-transport layer over the red, the green and the blue light-emitting materials by conducting a vapor-depositing process; and forming a metal layer over the electron-transport material by conducting a vapor-depositing process.
