A hinge coupling structure of a display device is provided to gradually control a rotation angle by modifying a shape of a bracket without using any springs, thereby preventing damage of the bracket caused by a torque of the spring. A hinge coupling structure of a display device includes a display bracket(20) mounted to a display part, and having a protruded rotation shaft(21). A step protrusion(22) is formed on an outer peripheral surface of the rotation shaft. A stand bracket(30) is formed with a coupling element(31) surrounding the outer peripheral surface of the rotation shaft, and formed with a plurality of concave and convex portions(32) inside, which are in the shape complementary with the step protrusion. The stand bracket is mounted to a stand.
