PROBLEM TO BE SOLVED: To provide a display device having a narrowed frame and a reduced thickness.SOLUTION: A display device includes: a display substrate having wiring lines on one surface and through-holes to the other surface at positions facing the wiring lines; and a wiring board provided on the other surface of the display substrate, and electrically connected to the wiring lines through the through-holes. The wiring board is connected to the wiring lines while keeping a planar state without being bent. As a result, the display device eliminates the need for a distance for bending the wiring board (a radius of curvature), achieving a narrowed frame and a reduced thickness.
Abstract:
The present invention provides for an electro-optic display having a backplane assembly with at least two electrode layers, a first electrode layer of a first dimension electrically connected to and driving a second electrode layer of a second dimension that is larger than the first dimension. The second electrode layer overlies the first electrode layer, such that the entire viewing area of an electro-optic display may be optically-active. The backplane assembly may have at least one interposer layer disposed between the two electrode layers to electrically connect the first and second electrode layers.

Abstract:
A tunable liquid crystal optical device defining an optical aperture and having a layered structure. The device includes a film electrode formed on a surface of a first substrate and covered by a second substrate, and a contact structure filling a volume within the layered structure and contacting the film electrode. The contact structure is located outside of the optical aperture and provides an electrical connection surface much larger than a thickness of the film electrode, such that reliable electrical connections may be made to the electrode, particularly in the context of wafer scale manufacturing of such a device.
