    Abstract: A touch sensor according to an embodiment of the present invention includes a base layer, a first electrode layer disposed on the base layer, and a second electrode layer disposed at an upper level of the first electrode layer. The first electrode layer includes a plurality of first sensing electrode rows extending in a first direction parallel to a top surface of the base layer, and first traces branched from each of the first sensing electrode rows and alternately distributed on both lateral portions of the base layer. The second electrode layer includes a plurality of second sensing electrode columns extending in a second direction that is parallel to the top surface of the base layer and intersects the first direction, and second traces branching from the second sensing electrode columns.

    Abstract: There is provided a flexible color filter for a display device, a flexible organic light-emitting display device comprising the color filter, and a manufacturing method therefor and, more specifically, a flexible color filter having a structure in which a base film, an adhesive layer, a separation layer, a protective layer, a black matrix layer, a pixel layer formed between different portions of the black matrix layer, and a planarization layer are sequentially stacked. The flexible color filter having the structure can be manufactured on a glass substrate, and thus advantages of solving a problem of thermal deformation of a plastic substrate in a high temperature process for implementing a color filter, enabling a fine pitch of a pattern, which cannot be implemented on a plastic substrate, and enabling diversification without limitations for a material of a base film can be secured.

    Abstract: A pad electrode part includes a plurality of pad electrodes transmitting a sensing signal of a sensing cell part to a flexible printed circuit board (FPCB). The pad electrode includes a plurality of widthwise arrangement groups arranged spaced apart in a width direction, and the plurality of widthwise arrangement groups are arranged to be spaced apart in a longitudinal direction as well. A pad electrode of the first widthwise arrangement group and a pad electrode of the second widthwise arrangement group have a same area but different lengths and widths.
