Abstract

PURPOSE: To improve the reliability of an electronic device and to reduce the thickness and size of the title device by uniting a displaying section and a part of a driving circuit integrally with a light transmissive conductive film on the light transmissive substrate for display and providing a conductor pattern 21, a part of which is brought into contact with the light transmissive conductive film and formed by hardening printed polymer type copper paste on the conductive film.
CONSTITUTION: A light transmissive conductive film is formed on the surface of, for example, a light transmissive lower glass substrate 6 forming a liquid crystal display element 1 by sputtering or vapor-depositing ITO, In2O3, SnO2, etc., after the surface of the substrate 6 is cleaned. After forming the conductive film, a light transmissive segment electrode 2 and transparent conductive film circuit 20 are formed by etching the light transmissive conductive film to required patterns. Moreover, a thick-film circuit section 22 is formed on the transparent conductive film circuit section 20 except a segment electrode 2 on the lower glass substrate 6 by laminating conductor patterns 21 by hardening printed polymer type copper paste. Therefore, the thickness and size of this electronic device can be reduced and the reliability of the device can be improved.
