Thereafter, the base film attached to the display panel through the film cutting unit of the film attaching device is moved along at least one of the longitudinal direction and the width direction of the base film so as to have a predetermined area corresponding to the display panel, The film can be cut (S16). Specifically, in the step of cutting the base film attached to the display panel, the film cutting unit may cut the base film so that the base film has a predetermined length corresponding to the length of the display panel, The base film can be cut.

In this way, according to the manufacturing method of the display device, the base film can be cut along the width direction of the base film after the display panel of the base film is attached through the film cutting unit during manufacturing of the display device .

Referring to FIG. 19, the display apparatus may supply the display panel and the film material including the base film through the panel supply unit and the film supply unit of the film attachment apparatus (S20).

Thereafter, the base film is peeled off from the release film of the film raw material through the adhering and peeling unit of the film adhering unit to separate the base film and the release film, and the base film Can be attached to the display panel (S22).

Thereafter, the base film attached to the display panel through the film cutting unit of the film attaching device is moved along the longitudinal direction and the width direction of the base film so as to have a predetermined length and width corresponding to the length and width of the display panel Each of the base films can be cut (S24).

According to the manufacturing method of the display device, when the display device is manufactured, the base film is cut in both the longitudinal direction and the width direction of the base film after the display panel is attached to the base film through the film cutting unit can do.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
