摘要： The present invention relates to a display device (10) capable of performing a touch input by a touch input device (20), and a touch input system including the same. According to an embodiment of the invention, a display device (10) comprising a display unit (DU) comprising a plurality of emission areas (EA1, EA2, EA3, EA4), a plurality of touch electrodes (SEN) disposed between the plurality of emission areas (EA1, EA2, EA3, EA4) to sense a touch, a plurality of code patterns (CP) formed by covering a part of a front surface of at least one of the plurality of touch electrodes (SEN) with a predetermined code shape, and a plurality of light-blocking patterns (DPd) formed on at least one of the plurality of touch electrodes (SEN) on which the plurality of code patterns (CP) is not formed, to block light, wherein the plurality of light-blocking patterns (DPd) is formed by covering at least one of a front surface and side surfaces of the at least one touch electrode (SEN) with a predetermined pattern shape.
