TOUCH PANEL AND ELECTRONIC DEVICE INCLUDING TOUCH PANEL
First Claim
1. A touch panel comprising:
- a first substrate on which a first resistive film is formed;
a second substrate on which a second resistive film is formed, the second substrate being arranged so that the second resistive film faces the first resistive film;
a frame-like seal member which is arranged between the first substrate and the second substrate to bond the first substrate to the second substrate;
an insulating spacer which is arranged in an area surrounded by the seal member and holds a space between the first substrate and the second substrate at a first thickness;
a protruding contact which is formed in the area surrounded by the seal member so as to protrude from the first substrate to the second substrate or from the second substrate to the first substrate and give a gap between the facing substrates; and
a liquid or liquid crystal which is sealed in the area surrounded by the seal member between the first substrate and the second substrate.

Abstract
A resistive film type touch panel includes first and second resistive films respectively provided on the inner surfaces of a pair of substrates on the touch side and the opposite side, protruding contacts which are provided on the first resistive film so as to protrude to a predetermined height, and come into contact with the second resistive film upon bending/deformation of the touch-side substrate by a touch to electrically connect the touch-side substrate to the second resistive film, insulating spacers which are arranged between the substrates except the positions of the protruding contacts, and define the space between the substrates to a height higher than that of protruding contacts, and a liquid or liquid crystal sealed in the space between the substrates. This arrangement reduces the bending/deformation amount of the touch-side substrate and the refraction of transmitted light at a portion bent/deformed by a touch on the touch-side substrate.
