Abstract: A method of manufacturing a display device, which is provided using an inkjet apparatus that provides a liquid composition including a scatterer, includes performing j scanning stages to provide a first composition to i unit display areas among n unit display areas (j is a natural number equal to or greater than 2), and performing a first compensation-scanning stage to provide the first composition to first to (i−1)-th unit display areas among the n unit display areas. The i unit areas of the first head unit provide the first composition to the first unit display area to an i-th unit display area among the n unit display areas in a first scanning stage among the j scanning stages. The first head unit is shifted in the second direction by one unit display area in every scanning stage of the j scanning stages.
