摘要 |
An EL display device free of a dispersion in the brightness caused by deterioration in the EL elements. The display device uses pixels of the current-controlled type to suppress a change in the current flowing through the EL elements caused by the deterioration in the EL elements. The display device further uses elements capable of short-circuiting or opening three nodes simultaneously. No bank is used for dividing the EL layers into separate colors. EL elements of the mixed junction type are used. A reverse bias voltage is applied to the EL elements at regular intervals. The display device suppresses dispersion in the brightness caused by the deterioration in the EL elements. |
