<P>PROBLEM TO BE SOLVED: To provide a touch panel device, which is provided with an electrostatic capacitance type touch sensor and a light emitting structure formed using light guide members, for preventing a gap (air layer) from being formed therebetween so as to perform an appropriate detection. <P>SOLUTION: A touch sensor device includes: light guide members 10; and a touch sensor 13 having a touch sensor pattern (electrode) that constitutes an electrostatic capacitance sensor on a surface opposite to the light guide members 10 on a substrate and is composed of a conductive material. Intermediate layers 11 and 12, which have a lower elastic modulus than that of light guide members 10 and are formed using a dielectric material, are interposed between the touch sensor 13 and the light guide members 10. The intermediate layers 11 and 12 are capable of preventing a gap (air layer) from being formed between the touch sensor 13 and the light guide members 10. Accordingly, an unstable touch detection attributed to the gap (air layer) can be prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
