1. A touch type liquid-crystal display device comprising:
a liquid-crystal display panel having flexibility; and
a touch panel disposed on a back side, opposite to a visual side, of said liquid-crystal display panel,
wherein said touch panel comprises at least a first pair of electrodes disposed to be opposite to each and separated by a gap, said first pair of electrodes being adapted for coming into partial contact with each other by a pressing force to thereby detect an input position, and
wherein said liquid-crystal display panel comprises a second pair of electrodes and a colored substrate provided on a touch panel side of said second pair of electrodes, and said first pair of electrodes are disposed on a back side, opposite to a visual side, of said colored substrate.
