Abstract

PURPOSE: To increase the display brightness of the luminous indicator by adding the reflecting agent to the substrate.
CONSTITUTION: The single substance of the paper, cloth and the like or the composition of these materials is used as the substrate material. And the varnish is made of the heat hardening resin such as the epoxy or the like, the heat-resisting resin such as the polyimide or the like or the mixture of these resin with addition of the hardening agent and the like if necessary. Then substrate material 1 is soaked into the varnish, or the varnish is coated to matetrial 1 with the solvent removed. Thus, the unit substrate of prepreg is produced after the drying process. This unit substrate is then stacked in the optional number of sheets to form a lamination. The lamination is then pressure-bonded along with the copper foil to form the lamination substrate. In this case, TiO2 of 15W25wt% is added as the reflecting agent into the resin varnish. As a result, the brightness of the display screen can be increased, at the same time enhancing the wire bonding characteristics.
