Zusammenfassung:The present invention is to provide a touch sensor with a fingerprint sensor capable of making brightness uniform by removing a difference in brightness in a portion to which a touch sensor and the fingerprint sensor are applied, in which an output of a touch display device of uniform brightness may be obtained by applying dummy electrodes to a portion constituting the touch sensor to change a structure so that light transmittances of the fingerprint sensor and the touch sensor are the same as or similar to each other or controlling a portion at which the finger sensor is positioned in an entire region of a light emitting layer to be brighter than the rest portion by a control unit of touch display devices to which the fingerprint sensor according to various embodiments of the present invention is applied.
