Abstract:
1. An electrophoretic display device, comprising: a first substrate comprising switching elements and driving electrodes; an electrophoretic display element layer fixed on a predetermined display region of the first substrate; a sealing member formed to surround the display element layer on the first substrate, the sealing member being thicker than the display element layer; and a second substrate fixed on an opposite end of the sealing member to the first substrate, the second substrate having a wider area than the display element layer, wherein the first substrate, the sealing member, and the second substrate form a closed inner space around the display element layer, thereby enclosing the display element layer in the space, wherein the space is filled with an inert gas having a pressure approximately equal to an atmospheric pressure or is set in a predetermined vacuum state, wherein the sealing member comprises an opening that allows an access to the electrophoretic display element layer enclosed in the space, the opening being closed by a closing member, and wherein a part of the closing member is drawn in the space by way of the opening.
