Abstract
In a chip mounting portion, a plurality of chip terminals arranged in a row and a plurality of terminal wiring lines corresponding to the plurality of chip terminals, the plurality of terminal wiring lines extending parallel to one another and being electrically connected to the plurality of chip terminals, respectively, are provided. For at least one chip terminal of the plurality of chip terminals, a chip support body is provided at each terminal wiring line with the chip support body overlapping the terminal wiring line corresponding to the at least one chip terminal or an extension line of the terminal wiring line.
Claims20
A display device comprising:
- a flexible substrate layer;
- a thin film transistor layer provided on the flexible substrate layer, the thin film transistor layer comprising a first flattening film, a wiring line layer, and a second flattening film layered, in this stated order, on the flexible substrate layer;
- and
- a light-emitting element layer provided on the thin film transistor layer, and comprising a plurality of light-emitting elements, the plurality of light-emitting elements arrayed such that each of the plurality of light-emitting elements corresponds to one of a plurality of subpixels that forms a display region;
- a frame region provided around the display region;
- a terminal portion extending in one direction and provided at an end portion of the frame region;
- a chip mounting portion provided between the display region and the terminal portion;
- a plurality of chip terminals arranged in a row in the chip mounting portion;
- and
- a plurality of terminal wiring lines corresponding to the plurality of chip terminals, the plurality of terminal wiring lines extending parallel to one another and being electrically connected to the plurality of chip terminals, respectively,
- wherein in the chip mounting portion, for at least one chip terminal of the plurality of chip terminals, a chip support body is provided, the chip support body overlapping one of a terminal wiring line that corresponds to the at least one chip terminal or an extension line of the terminal wiring line corresponding to the at least one chip terminal, the chip support body comprising:
- a lower resin layer made of the same material as that of the first flattening film, and formed in the same layer as that of the first flattening film, and
- an upper resin layer provided on the lower resin layer, made of the same material as that of the second flattening film, and formed in the same layer as that of the second flattening film.
