Abstract: A sensor of recognizing finger prints using micro lens is provided to maximize the amount of incident light to an optical measuring area by comprising the micro lens including a spherical lens varying a path of the light. In a sensor of recognizing a finger print using micro lens(500), the micro lens varies a path of light which is reflected by a finger mark structure. An optical thin film transistor(300) arranged separately from the micro lens recognizes the finger mark structure by the varied light in the path. A spherical lens(510) having a convex shape with a regular curvature is placed at one side of the micro lens, heading for the thin film transistor.
