Abstract
The present invention provides a display device, a method for producing a display device, and a method for inspecting a display device, which are capable of inspecting, after bonding of a display panel and a FPC to each other, a conductive line formed near an edge of the display panel and/or an edge of the FPC for open circuits, partial open circuits, and short circuits. The display device includes: a display panel; a flexible printed circuit connected to the display panel; and an inspection line formed along one or both of an edge of the display panel and an edge of the flexible printed circuit and including a capacitance-forming portion that exhibits capacitance.
Claims16
A display device comprising:
- a display panel;
- a flexible printed circuit connected to the display panel;
- and
- an inspection line formed along one or both of an edge of the display panel and an edge of the flexible printed circuit and including a capacitance-forming portion that exhibits capacitance.
A method for producing a display device including a display panel and a flexible printed circuit connected to the display panel, the method comprising:
- forming, along one or both of an edge of the display panel and an edge of the flexible printed circuit, an inspection line including a capacitance-forming portion that exhibits capacitance;
- connecting the flexible printed circuit to the display panel;
- and
- measuring capacitance of the inspection line after the connecting so as to inspect the inspection line for open circuits, partial open circuits, or short circuits based on the measured capacitance.
A method for inspecting a display device including a display panel and a flexible printed circuit connected to the display panel,
- the display device comprising an inspection line formed along one or both of an edge of the display panel and an edge of the flexible printed circuit and including a capacitance-forming portion that exhibits capacitance,
- the method comprising
- measuring capacitance of the inspection line so as to inspect the inspection line for open circuits, partial open circuits, or short circuits based on the measured capacitance.
