Abstract

A display unit manufacturing method according to embodiments of the present invention may comprise the steps of: preparing an optical film; forming a first alignment mark on the optical film; forminga cutting line corresponding to a predetermined closed-curve layout on the optical film on the basis of the position of the first alignment mark; preparing a panel having a second alignment mark formed thereon; aligning at least one of the optical film and the panel with the other on the basis of the position of the first and second alignment marks; and laminating the post-processing optical film,on which the cutting line is formed, on the panel.

Description

technical field [0001] The present invention relates to a method of manufacturing a display unit by laminating a film on a panel. Background technique [0002] The display unit may be manufactured by attaching an optical film including a polarizer to the surface of the panel. A liquid crystal panel having a liquid crystal layer or an organic EL panel having an OLED layer can be used as the panel. [0003] In general, the layout of a panel for a display unit may be quadrangular, in particular, rectangular. [0004] Meanwhile, an optical film having a quadrangular layout corresponding to that of the panel is attached to the panel having the quadrangular layout. [0005] In this case, a process of aligning the positions of the panel and the optical film is required so that the layout of the panel and the layout of the optical film correspond to each other before attaching the panel and the optical film to each other. Since both the layout of the panel and the layout of the o...
