Abstract:
A touch panel for a display device, comprising:a pair of resistive layers disposed facing each other across a plurality of insulating dot spacers, a first resistive layer being laid on a flat translucent hard plate, said translucent hard plate facing toward a display surface of said display device; and a front light unit interposed between said display surface of said display device and said pair of resistive layers, said front light unit comprising a light source and a light conductive plate in which an array of prisms, whose respective ridges are parallel to each other, is formed on a surface opposite to a surface facing said display device so as to guide light emitted from said light source toward said display surface of said display device; the touch panel being adapted to generate a signal by touching an outer surface of a second resistive layer according to a position touched, wherein said light conductive plate and said translucent hard plate are integrally combined with each other and sandwich elastic spacers therebetween.
