PURPOSE: A hinge device for a display is provided to use a common bolt without using a special hinge shaft, to prevent the abrasion of a plate by relative rotation, to control the inclination of a display without using separate components and to reduce the manufacturing cost. CONSTITUTION: The hinge device for a display comprises a primary movable plate(10) fixed on the backside of the display and provided with a perforation hole(13), a secondary fixed plate(20) connected with a stand of the display and provided with another perforation hole(23), a hinge shaft(30) coupled with the perforation holes(13,23) of the primary and secondary plates(10,20) and provided with a head, a nut(70) as a coupler fixed on the end of the hinge shaft(30), a primary washer(41) placed between the head of the hinge shaft(30) and the primary movable plate(10), primary and secondary fixed washers(51,52) fixed to both sides of the perforation hole(13) of the primary plate(10), and third and fourth fixed washers(53,54) fixed to both sides of the perforation hole(23) of the secondary plate(20), wherein at least one of the fixed washers(51,52,53,54) is an elastic washer which transfers axial compressive elasticity. |
