Electronic paper display device

An electronic paper display device comprises an upper supporting layer, a lower supporting layer and an electronic ink layer. And the lower supporting layer is opposite to the upper supporting layer. At least one of the upper support layer and the lower support layer has a thickness in the range of 1 [mu] m to 50 [mu] m and a storage modulus at 0 DEG C to 70 DEG C in the range of 1 kPa to 100 kPa. The electronic ink layer is located between the upper support layer and the lower support layer. At least one of the upper supporting layer and the lower supporting layer can reduce shearing force borne by the electronic ink layer in the bending process, and system stress is effectively reduced. 一种电子纸显示装置包括上支撑层、下支撑层与电子墨水层。下支撑层与上支撑层相对。上支撑层与下支撑层至少其中一者的厚度在1μm至50μm的范围中且于0℃至70℃的储存模数在1kPa至100kPa的范围中。电子墨水层位于上支撑层与下支撑层之间。前述上支撑层与下支撑层至少其中一者可降低电子墨水层在弯折过程中受到的剪力，有效降低系统应力。
