Abstract: A substrate conductive bonding structure includes a lower substrate including a connection pad exposed to outside the lower substrate, an upper substrate including a transfer pad overlapping the connection pad, exposed to outside the upper substrate and including an upper surface, and a slit defined in the transfer pad, overlapping the connection pad and open at the upper surface of the transfer pad, the slit including an extending portion extending along a first direction and having a first slit width along a second direction crossing the first direction, and an expansion portion connected to the extending portion and having a second slit width along the second direction which is larger than the first slit width, and a solder contacting the upper surface of the connection pad, extending to the upper surface of the transfer pad and into the slit.

Abstract: A manufacturing method of a display device includes providing a display module including a display panel, a first flexible circuit board disposed at a first side edge of the display panel, a window disposed on the display panel, and an optical film disposed between the display panel and the window on the stage; aligning the display module such that the first side edge is disposed under the bonding unit; moving the position detection sensor along the first side edge of the display module to sense a first coating path; moving the resin supply unit along the sensed first coating path to coat a first filling agent between the window and the display panel; and moving the light irradiation unit along the sensed first coating path to cure the coated first filling agent to form a first filling layer.

Abstract: A display device includes a stage, a bonding unit disposed on the stage and comprising a position detection sensor, a resin supply unit, and a light irradiation unit, and a fixing unit disposed closer to the stage than the bonding unit is to fix a target member. Embodiments align a display module such that a first side edge of the display module is disposed under the bonding unit. Embodiments move the position detection sensor along the first side edge of the display module to sense a first coating path; move the resin supply unit along the sensed first coating path to coat a first filling agent between the window and the display panel; and move the light irradiation unit along the sensed first coating path to cure the coated first filling agent to form a first filling layer.
