Abstract

An apparatus for fabricating an organic light emitting display panel is disclosed. In one embodiment, the apparatus includes i) a first roll around which a film is wound to be continuously drawn, ii) a second roll arranged to face the first roll and around which the film is continuously wound, iii) a plurality of chambers disposed between the first and second rolls and through which the film passes, and in which laser induced thermal imaging (LITI) is performed on a substrate by forming a transfer layer on the film, and iv) a gate unit installed at least one of the chambers and disposed at at least one of a film inlet and a film output of the chambers that are installed, to maintain a substantially vacuum state in the chambers during passing of the film.
