Efficacy, detailed as follows.

FIG. 2 is a schematic perspective view of a display provided by an embodiment of the present invention. Referring to FIG. 2 , the display 200 is, for example, an electronic paper display, which includes an active device array substrate 210 , a display layer 220 and a transparent shock absorbing layer 230 . The transparent impact-absorbing layer 230 is disposed on the active device array substrate 210 , and is formed, for example, by curing a liquid adhesive. The display layer 220 is arranged between the active element array substrate 210 and the transparent shock absorbing layer 230, and the display layer 220 in this embodiment can be a microcup type electrophoretic layer, a microcapsule type electrophoretic layer, an electrowetting layer or an electronic powder layer, etc., but the present invention is not limited thereto.

In detail, the active device array substrate 210 includes a substrate 212 , a thin film transistor array (not shown in the figure) and a driving circuit 213 . The substrate 212 is made of glass, the thin film transistor array is disposed on the substrate 212 , and the driving circuit 213 is disposed on the edge of the substrate 212 and is electrically connected with the thin film transistor array for transmitting signals to the thin film transistor array.

In particular, since the transparent impact-absorbing layer 230 is formed by curing liquid adhesive, the display 200 of this embodiment may further include a frame body 240 for the convenience of arranging the transparent impact-absorbing layer 230, and the frame body 240 is disposed on the display layer 220. On the premise of not affecting the visible range of the display 200 , it is arranged along the edge of the display layer 220 , and the transparent impact-absorbing layer 230 is formed in the frame body 240 .
