Claims
- 1. A method for manufacturing an electroluminescent lighting element, comprising the steps of:
- applying a light permeable paste in a predetermined pattern by screen printing on an insulating transparent film serving as a base material, and then forming a transparent electrode layer by performing a photo-hardening or thermal-hardening operation, to form a predetermined light-emitting region offset from an external connecting terminal of said insulating transparent film;
- applying a light-emitting paste in a predetermined pattern by screen printing on said transparent electrode layer, and then forming a light-emitting layer corresponding to said light-emitting region on said transparent electrode layer by performing a heating and drying operation;
- applying a dielectric paste in a predetermined pattern by screen printing on said light-emitting layer, and then forming a dielectric layer on said light-emitting layer by performing a heating and drying operation;
- applying a conductive paste in a predetermined pattern by screen printing on said dielectric layer, and then forming a back-surface electrode layer on said dielectric layer by performing a heating and drying operation;
- applying a conductive paste in a first pattern by screen printing in such a manner that one end of said first pattern is connected to said transparent electrode layer and the other end of said first pattern constitutes part of an external connecting terminal, and also applying a conductive paste in a second pattern by screen printing in such a manner that one end of said second pattern is connected to said back-surface electrode layer and the other end of said second pattern constitutes part of said external connecting terminal, and then forming first and second collecting electrodes by performing a heating and drying operation; and
- applying an insulating paste by screen printing on an entire surface of said electroluminescent lighting element except for a distal end of said external connecting terminal, and then forming an insulating coat layer by performing a heating and drying operation.
- 2. The manufacturing method in accordance with claim 1, wherein said back-surface electrode layer and said collecting electrodes are integrally formed in a predetermined pattern.
- 3. The manufacturing method in accordance with claim 1, wherein said collecting electrodes are formed before said transparent electrode layer is formed.
