Abstract

THERE IS PROVIDED A FRONT LIGHT-COMBINED TOUCH PANEL DEVICE WHICH CAN SUFFICIENTLY ILLUMINATE A REFLECTING TYPE LIQUID CRYSTAL DISPLAY WITHOUT LOWERING TRANSMITTANCE. A TRANSPARENT TOUCH PANEL (13) IS USED WHICH COMPRISES: AN UPPER ELECTRODE PLATE (9) HAVING AN UPPER ELECTRODE FORMED ON A LOWER FACE OF A FILM-LIKE INSULATING SUBSTRATE; AND A LOWER ELECTRODE PLATE (11) HAVING A LOWER ELECTRODE FORMED ON AN UPPER FACE OF A PLATE-LIKE OR FILM-LIKE INSULATING SUBSTRATE WITH MINUTE PROJECTIONS AND DIPS (8) ARRANGED ON THE UPPER FACE THEREOF, IN WHICH THE UPPER ELECTRODE PLATE (9) AND THE LOWER ELECTRODE PLATE (11) ARE ARRANGED TO FACE EACH OTHER VIA AN AIR LAYER BETWEEN THE ELECTRODES, AND THE LIGHT GUIDE PLATE (3) IS BONDED TO A REAR FACE OF THE TRANSPARENT TOUCH PANEL (13) VIA A SELF-ADHESIVE LAYER (12) OR RE-LEASE SHEET, AND A LIGHT SOURCE (4) IS SET AT AN END FACE OF THE LIGHT GUIDE PLATE (3), SO THAT THE TRANSPARENT TOUCH PANEL (13) AND THE FRONT LIGHT DEVICE (2) ARE COMBINED IN ONE BODY.(FIG 1)
