A method for manufacturing an image display element including: a front panel; a back panel facing the front panel; plural pixels arranged in a matrix between the panels, and to be selected to be in a display or non-display state; and plural electrodes for controlling the pixels, the panels being bonded with the pixels and the electrodes interposed therebetween, and the electrodes being connected to a driving control circuit via metal wires, includes a first step of performing dicing from the back side of the opposing surface from the front panel, and forming a groove part such that electrode terminals connected to the electrodes are exposed between adjacent plural pixel lines, with the back panel bonded thereto, and a second step of forming the metal wires so as to be connected to the electrode terminals exposed at the groove part.

Method for manufacturing image display element

An image display element includes: a front panel; a back panel opposite thereto; a plurality of pixels arranged between both the panels; and plural electrodes for controlling the pixels. The panels are bonded with the pixels and the electrodes interposed therebetween, and the electrodes are connected to a driving circuit via metal film wires. The back panel is divided so as to expose electrode terminals, and a groove part V-shaped in cross section is formed at the divided portion. The metal film wires are formed on the top surface of the back panel, and the electrode terminals and the metal film wires are connected by a conductive paste coated along the tilt surfaces forming the groove part. Partitions are disposed between the adjacent electrode terminals at the bottom of the groove part.

Image display element and manufacturing method thereof

An image display element includes: a front panel; a back panel opposite to the front panel; a plurality of pixels arranged in a matrix between both the panels, and to be selected to be in a display or non-display state; and plural electrodes for controlling the pixels. Both the panels are bonded together with the pixels and the electrodes interposed therebetween, and the electrodes are connected to a driving control circuit via metal wires. The back panel is divided such that electrode terminals connected to the electrodes are exposed between adjacent plural pixel lines, and a groove part having a shape wider at the top on the back side of the opposing surface from the front panel than at the bottom is formed at the divided portion. The metal wires are connected to the exposed electrode terminals of the groove part.

Image display element with divided back panel and manufacturing method thereof

An image display element includes: a front panel; a back panel opposite thereto; a plurality of pixels arranged in a matrix between both the panels; and plural electrodes for controlling the pixels. Both the panels are bonded together with the pixels and the electrodes interposed therebetween, and the electrodes are connected to a driving circuit via metal film wires. Division is performed so as to expose electrode terminals, and a groove part V-shaped in cross section is formed at the divided portion. The metal film wires are formed on the surface of the top of the back panel, and the electrode terminals and the metal film wires are connected by a conductive paste coated along the tilt surfaces forming the groove part.

Image display element with a divided back panel

An image display element includes: a front panel; a back panel opposite thereto; plural pixels arranged in a matrix between the panels; and plural electrodes for controlling the pixels. The panels are bonded with the pixels and the electrodes interposed therebetween. The electrodes are connected to a driving circuit via metal film wires. The back panel is divided so as to expose electrode terminals, and a groove part V-shaped in cross section is formed at the divided portion. The metal film wires are formed on the top surface of the back panel, and the electrode terminals and the metal film wires are connected by a conductive paste coated along the tilt surfaces forming the groove part. A contact resistance reducing means is disposed at the connection part interface between the electrode terminal and the conductive paste.
