A touch sensor includes a first sensing cell part and a first wiring part. The first sensing cell part arranges first sensing cell line groups by a first repetition number to be spaced apart in an X-axis direction. The first wiring part is formed in one outer bezel area in a Y-axis direction from the first sensing cell part. The first wiring part includes a first outgoing wire group connected to the first sensing cell line group and a first dummy wire group not connected to the first sensing cell line group.

Touch sensor

A touch sensor comprises a group pattern having a sensing cell part including a plurality of sensing cell groups in which a plurality of sensing cells are electrically connected and a wiring part formed outside the sensing cell part. The wiring part includes a first sub-wiring part and a second sub-wiring part. The first sub-wiring part has a drawing wire electrically connected to a sensing cell at one end of the sensing cell group. The second sub-wiring part is disposed outside the first sub-wiring part and has a non-drawing wire not electrically connected to the sensing cell part. The non-drawing wires are provided as many as the number of unit patterns repeatedly formed to constitute a large-area touch sensor minus one.

Touch sensor and exposure mask for forming same

A light control plateA of the present invention is disposed in front of a surface light sourcethat emits, in a predetermined direction, parallel light Fhaving a substantially uniform luminance distribution. The light control plateA has a light incidence surface, at which there are provided optical path control sectionsA of concave and/or convex cross-sectional shape, and a planar light exit surface. The surface of the optical path control sectionsA comprises first to M-th planar portionsAtoA. The inclination angles &#x3b1;to &#x3b1;and pitch ratios Lto Lof each planer portion are specified in such a manner that the parallel light Fcan be spread within an exit angle range &#x2212;&#x3b8;to &#x3b8;relative to the predetermined direction, to exit as light having a substantially uniform luminance angular distribution within the exit angle range. Thereby, parallel light having a uniform luminance distribution can be spread within a predetermined angle range, to exit as light having a substantially uniform luminance angular distribution within the angle range.
