The goal of this study is optimization of transparency liquid chemical coating process. At coating process in the maintenance of the coating gap is an important factor. Specially, at a small split from the substrate using the existing methods is difficult to maintain the uniformity of coating. In this study, slit coating uniformity and compare inkjet uniformity and thickness profile was analyzed using alpha-step. Also, the pencil hardness test and the color difference measurement were performed. As a result, changes of the coating process need to be made depending on the type of substrate and inkjet coating was suitable for substrate of a small split.
