Abstract

A touch sensor according to one embodiment of the present invention comprises: a base layer including a first region and a second region; a touch sensing electrode layer which is arranged on the first region of the base layer and which includes a plurality of touch sensing unit electrodes having openings formed therein; and a fingerprint sensing electrode layer which includes a plurality of fingerprint sensing unit electrodes arranged on the second region of the base layer and which contains a space having the same shape as the opening between the adjacent fingerprint sensing unit electrodes. Electrode visibility is prevented by the opening and the space and transmittance can be increased.

Description

technical field [0001] The present invention relates to a touch sensor and an image display device including the touch sensor. More particularly, the present invention relates to a touch sensor including patterned sensing electrodes and an image display device including the same. Background technique [0002] With the development of information technology, various demands for display devices having thinner dimensions, light weight, high-efficiency power consumption, and the like are increasing. The display device may include a flat panel display device such as a liquid crystal display (LCD) device, a plasma display panel (PDP) device, an electroluminescent display device, an organic light emitting diode (OLED) display device, and the like. [0003] A touch panel or a touch sensor capable of inputting a user's instruction by selecting an instruction displayed on a screen with a finger or an input tool is also being developed. A touch panel or a touch sensor can be combined ...
