Abstract: A panel bottom assembly includes a light-blocker with first concave patterns formed on a top surface thereof. A vibration acoustic device is disposed below, and coupled to, the light-blocker. A buffer is disposed below the light-blocker. A bonding is disposed between the light-blocker and the vibration acoustic device. The bonding has second concave patterns formed on a top surface thereof. The second concave patterns are different from the first concave patterns.

Abstract: An apparatus for manufacturing a display device comprises a stage, a panel cell disposed on the stage and including a first alignment line, and a second alignment line extending parallel to the first alignment line, a field application part providing an alignment signal to the first alignment line and the second alignment line of the panel cell, and light-emitting elements aligned between the first alignment line and the second alignment line. The field application part provides an alignment signal to the first alignment line and the second alignment line, the alignment signal having the same positive integral value and negative integral value, having a different positive peak voltage from the alignment signal's negative peak voltage, and having a different positive pulse width from the alignment signal's negative pulse width.
