ABSTRACT:
A color display device using an electroluminescent polymer includes: a transparent substrate; a transparent electrode formed on the transparent substrate, the electrode being buried by a luminescent polymer; a photo-bleached region (non-luminous region) of a first luminescent polymer formed on the transparent electrode; a non-photo-bleached region (luminous region) of a first luminescent polymer formed between a portion of the transparent electrode and a first metal electrode; a photo-bleached region (non-luminous region) of a second luminescent polymer formed on the photo-bleached region of the first luminescent polymer; a non-photo-bleached region (luminous region) of a second luminescent polymer formed between a portion of the photo-bleached region of the first luminescent polymer and a second metal electrode; a first metal electrode formed on the non-photo-bleached region of the first luminescent polymer; a photo-bleached region (non-luminous region) of a third luminescent polymer formed on the photo-bleached region of the second luminescent polymer; a non-photo-bleached region (luminous region) of a third luminescent polymer formed between a portion of the photo-bleached region of the second luminescent polymer and a third metal electrode; a second metal electrode formed on the non-photo-bleached region of the second luminescent polymer; and a third metal electrode formed on the non-photo-bleached region of the third luminescent polymer.
