Anti-pressing back cover of portable computer display panel

A display panel protecting back cover for a portable computer comprising a rectangle frame which is composed of continuous defining of a first relative lateral edge pair and a second relative lateral edge pair, a first end wall pair which is approximately vertically extended through the separate first relative edge pair, a second end wall pair which is vertical to the second relative lateral edge pair and extended in the same direction with the first end wall pair, a first bumper pair which is lined on the inner side wall of the first end wall pair, a second bumper pair which is lined on the inner side wall of the second end wall pair, a copping which connects the continuous surfaces of the first relative lateral edge pair and the second relative lateral edge pair. The continuous surface of the copping is a stress dispersive structure which is projected opposite to the extensive direction of the first end wall pair and the second end wall pair, thereby achieving the effect of protecting the display panel.
