    Abstract: An inkjet printing apparatus includes: a stage, which reciprocates in forward and reverse directions opposite to each other and has a target substrate disposed thereon; an inspection device including a film disposed outside the stage and a measurement unit which measures an inspection pattern provided on the film; and a head assembly, which moves along one direction crossing the forward direction and has a plurality of heads which supplies a liquid composition to the target substrate. The head assembly moves in the one direction to overlap the film and sprays the composition onto the film to form an inspection pattern.

    IPC: H01L27/32

    Abstract: A display device includes a first region including a first light emitting element including a first electrode, a second region including a second light emitting element including a second electrode, a pixel defining layer including a first sidewall defining a first opening corresponding to the first electrode and a second sidewall defining a second opening corresponding to the second electrode, a first spacer which protrudes from the pixel defining layer in the first region and includes a first edge closest to the first opening, and a second spacer which protrudes from the pixel defining layer in the second region and includes a second edge closest to the second opening. A distance between the first sidewall and the first edge, is smaller than a distance between the second sidewall and the second edge.

    IPC: B41J2/165

    Abstract: A head cleaning method includes contacting a nozzle surface of a head in which nozzle holes are defined with an absorbent on a pressurizer, starting a wiping operation at a first edge portion of the head closest to the pressurizer at a first position, and ending the wiping operation at a second edge portion of the head furthest away from the pressurizer at the first position, positioning the pressurizer at a second position to define a first angle between a first imaginary line parallel to a longitudinal direction of the head and a second imaginary line parallel to a longitudinal direction of the pressurizer, and starting the wiping operation at a third edge portion of the head closest to the pressurizer at the second position, and ending the wiping operation at a fourth edge portion of the head furthest away from the pressurizer at the second position.
