Abstract: A method for manufacturing an LED lighting device includes forming a separation film on a substrate, patterning the separation film, forming LEDs on the separation film, bonding a stretch film to top surfaces of the LEDs and spacing between the LEDs, separating the separation film from the substrate, stretching the stretch film, exposing the top surfaces of the LEDs, and forming electrodes on the top surfaces of the LEDs, and a bottom surface of the separation film or bottom surfaces of the LEDs.

Abstract: 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.

Abstract: A light control plate 30A of the present invention is disposed in front of a surface light source 20 that emits, in a predetermined direction, parallel light Fi having a substantially uniform luminance distribution. The light control plate 30A has a light incidence surface 30a, at which there are provided optical path control sections 31A of concave and/or convex cross-sectional shape, and a planar light exit surface 30b. The surface of the optical path control sections 31A comprises first to M-th planar portions 32A1 to 32AM. The inclination angles ?1 to ?M and pitch ratios L1 to LM of each planer portion are specified in such a manner that the parallel light Fi can be spread within an exit angle range ??max to ?max relative to the predetermined direction, to exit as light having a substantially uniform luminance angular distribution within the exit angle range.
