Electronic paper display device

Abstract

An electronic paper (E-paper) display device includes a pixel array substrate, an E-paper display layer, a driving circuit carrier, an adhesive, and an edge conductive patter. The pixel array substrate has a display surface, a back surface opposite to the display surface, and a sidewall connected between the display surface and the back surface. The E-paper is disposed on the display surface. The driving circuit carrier is disposed on the back surface and is adhered to the back surface through the adhesive. A sidewall of the adhesive and the sidewall of the pixel array substrate are connected to form a composite sidewall. The edge conductive pattern physically contacts the pixel array substrate, the adhesive and the driving circuit carrier and includes a first plane portion on the display surface, a second plane portion on the back surface and a vertical portion disposed on the composite sidewall and extending between the first plane portion and the second portion.
