US 2003/0146969 A1 · Exposure apparatus

Abstract

A plurality of cathode lines are formed as scanning electrodes on a transparent substrate, and metal cathodes of the same cathode line apply a common potential to organic electroluminescence elements that are arranged in a main-scanning direction in the same element row. A plurality of anode lines are formed as data electrodes on the transparent substrate, so as to intersect the plurality of cathode lines and incline at a predetermined angle θ with respect to a sub-scanning direction. Transparent anodes of the same anode line apply a common potential to organic electroluminescence elements having mutually different positions in the sub-scanning direction. Organic electroluminescence elements that use the same anode line have mutually different positions in the main-scanning direction. Organic electroluminescence elements that have the same position in the main-scanning direction use mutually different anode lines.

Dependent claims

An exposure apparatus comprising;

a plurality of line-shaped scanning electrodes which are arranged in a sub-scanning direction and control scanning in a main-scanning direction;
a plurality of line-shaped data electrodes which are arranged in the main-scanning direction and control scanning in the sub-scanning direction;
and
a plurality of light emitting elements, each of which is formed at an intersection of one of the plurality of scanning electrodes and one of the plurality of data electrodes and emit light by receiving a voltage applied by one of the plurality of scanning electrodes and one of the plurality of data electrodes,
wherein each of the plurality of data electrodes is arranged at a predetermined angle with respect to the sub-scanning direction so that light emitting elements formed along different data electrodes expose substantially the same position on an exposure subject in the sub-scanning direction.
