Abstract: A rollable display device includes: a panel supporting portion including a plurality of supporters arranged in substantially parallel relationship and a plurality of hinge linking portions rotatably connecting adjacent supporters to one another, and having rolled and unrolled configurations; a flexible display panel having a display area disposed on the panel supporting portion and a non-display area outside the display area; and a driving module including a flexible circuit board having a bent portion and connected to the non-display area, and a printed circuit board (PCB) connected to the flexible circuit board. The plurality of supporters includes a housing disposed at an outermost side of the rollable display device. The housing has a hole through which the non-display area passes and a chamber communicating with the hole and receiving the driving module. A sealant is disposed between the flexible display panel and the housing at the outside of the hole.

Abstract: A method of attaching a polarizer includes preparing a first stage on which a display panel is disposed and a second stage on which a first polarizer is disposed, measuring a shape of a curl of the first polarizer; determining an attachment direction of the first polarizer with respect to the display panel based on the measured curl shape of the first polarizer and attaching the first polarizer to a first surface of the display panel by rotating at least one of the first stage and the second stage based on the determined attachment direction.
