    Abstract: In a method of manufacturing a display device, first and second panels are aligned by using an alignment apparatus. The first panel includes pixel driving circuits arranged on a first substrate, each of the pixel driving circuits includes a transistor and a pixel electrode connected to the transistor, and the second panel includes light emitting elements arranged on a second substrate. An end portion of at least one of the light emitting elements is bonded to the pixel electrode by using a bonding apparatus, and a lighting test is performed on a mother panel by using a test apparatus. The mother panel includes the first panel and the second panel, and is divided into a plurality of display panels in plan view. A defect management map for the plurality of display panels is generated based on a result of the lighting test.

    Abstract: A force sensor includes first and second substrates. The second substrate faces the first substrate. A driving electrode is disposed on a first surface of the first substrate facing the second substrate. A sensing electrode is disposed on the first surface of the first substrate and is spaced apart from the driving electrode. A three sensitive layer is disposed on a first surface of the second substrate, facing the first substrate. The driving electrode includes a main driving protrusion that protrudes from a side surface of the driving electrode, facing the sensing electrode.
