Title: Organic el element
Inventor: KURIYAMA TAKAYOSHI
IPC: H05B33/12
Filed: 2001-04-13
Abstract: PROBLEM TO BE SOLVED: To provide an organic EL element that can change a luminous color tone without needing a plurality of signal lines for every picture element. SOLUTION: Organic EL laminated bodies 3a, 3b of this organic EL element 1A are arranged to be visible as a square picture element as a whole. When the luminous layers of organic EL films used for the organic EL element 1A emit light of the same brightness, the resistance of the organic EL film 32b is higher than that of the organic EL film 32a at first, but when driven for a long time, the resistance of the organic EL film 32a becomes higher than that of the organic EL film 32b. In such an organic EL element, it is not necessary to add the signal line for changing the color tone, and the luminous color tone can be changed using a driving circuit of the conventional organic EL element as it is. Furthermore, the composition of the organic EL films can be easily determined from the color tone required for operation.
