Document Type and Number:

WIPO Patent Application WO/2002/097837

Kind Code:

A1

Abstract:

A thin and light member (1) for push button switch having high visibility in which illumination of uniform luminance can be realized at a display section while suppressing power consumption by using optical energy effectively for illumination at the display section. The member (1) for push button switch comprises a key top section (3), a cover basic material being fixed onto a circuit board (5) while arranging the key top section (3) at a specified position, and a surface light emitter (4) integral with a switch function display section (2) disposed at the key top section (3). The surface light emitter (4) has an emission layer (13) formed between a base electrode (14) and a transparent electrode (10) facing the base electrode (14), wherein the transparent electrode (10) disposed contiguously to the display section (2) is made of a transparent conductive polymer.
