Abstract
In a display device in which a display panel is supported from the back by a back frame, the back frame is composed of a pair of long side portions and a pair of short side portions each having an angular structure in section. Whereby, torsional strength is increased while suppressing increase in weight. This leads to increase in torsional strength while suppressing increase in weight even in a large-sized display screen.
