- the passive matrix type organic EL display device shown is the same as that of FIG. 2, but in this embodiment, a plurality of ITO scanning electrode patterns 22 A indicated by stars in the drawing are shown. Are simultaneously driven to perform a desired display.
- the interval between the ITO electrode patterns 22 A that are simultaneously driven is set so that only one pixel emits light on the same data electrode pattern 24 A. Accordingly, an image can be displayed by a driving method similar to that of the conventional display device 10 in which the ITO scanning electrode pattern 12A of FIG. 1 extends in the lateral direction of the substrate.
- the present invention has been described with respect to a passive matrix type organic EL display device.
- the present invention is not limited to a display device using such a specific light emitting element.
- the present invention can be applied to other light emitting devices having the same, for example, a light emitting device using an LED array.
- the passive matrix light-emitting device of the present invention also includes a liquid crystal display device equipped with a packlight. .
- a surface light source can be realized. Further, in such a surface light source, it is possible to adjust the brightness of the illumination by controlling the numbers of the selected scanning electrode patterns 22 A and data electrode patterns 24 A.
- the drive electrode since the drive electrode forms an angle other than a right angle or a right angle with respect to an arbitrary side of the display area, even if the substrate is horizontally long, the drive electrode includes a plurality of drive electrodes. It is not necessary for each of the scanning lines to extend continuously from one end to the other end in the long side direction of the display area, and accordingly, a voltage drop in the scanning line is suppressed, and the light emission intensity of the light emitting element Is reduced. As a result of the present invention, a passive matrix light emitting device having an arbitrary aspect ratio can be realized. Such a display device can be used not only as an information display device but also as a surface-emitting light source.
