Abstract: The present disclosure relates to a display panel fixing apparatus that adjusts a separation distance between first and second support frames by folding a link while an adjustment member of a gap adjustment unit is vertically moved, adjusts a height of a height adjustment unit in proportion to an exposure distance of a height adjustment bolt by vertically moving the height adjustment bolt, adjusts angles of upper end lower ends of a fixing frame while vertically moving and rotating angle adjustment members installed at upper and lower ends using a vertical movement adjuster of an angle adjustment device, and thus can individually finely adjust a separation distance between a display and a base frame, an installation height of a display, and tilting angles of upper and lower ends of the display.
