Abstract
To provide a display device including a flexible panel that can be handled without seriously damaging a driver circuit or a connecting portion between circuits. The display device includes a bent portion obtained by bending an element substrate. A circuit for driving the display device is provided in the bent portion and a wiring extends from the circuit, whereby the strength of a portion including the circuit for driving the display device is increased and failure of the circuit is reduced. Furthermore, the element substrate is bent in a connecting portion between an external terminal electrode and an external connecting wiring (FPC) so that the element substrate provided with the external terminal electrode fits the external connecting wiring, whereby the strength of the connecting portion is increased.
Claims9
A display device comprising:
- an element substrate having flexibility, the element substrate including a first portion, a second portion and a third portion, the third portion being adjacent to the first portion;
- a display portion provided over the first portion of the element substrate;
- and
- an external connecting electrode provided over the second portion of the element substrate,
- wherein the external connecting electrode is in contact with an external connecting wiring, and
- wherein the element substrate is bent so that the external connecting electrode and a part of the external connecting wiring are sandwiched between the second portion of the element substrate and the third portion of the element substrate.
A display device comprising:
- an element substrate having flexibility, the element substrate including a first portion and a second portion;
- a sealing substrate having flexibility;
- a display portion provided over the first portion of the element substrate;
- and
- an external connecting electrode provided over the second portion of the element substrate,
- wherein the element substrate has a larger area than the sealing substrate;
- and
- wherein the external connecting electrode is in contact with an external connecting wiring, and
- wherein the element substrate is bent so that the external connecting electrode and a part of the external connecting wiring are sandwiched by the element substrate.
