摘要

A display device includes a first guide member extending in a first direction, a second guide member extending in the first direction and facing the first guide member in a second direction crossing the first direction, a display panel disposed between the first guide member and the second guide member, a support member which supports a portion of the display panel, a first driving unit which moves the support member, and a second driving unit connected to one end of the display panel to roll or unroll the display panel. Both sides of the support member are inserted into guide grooves defined in an inner side surface of the first guide member and an inner side surface of the second guide member, which faces the inner side surface of the first guide member, and the support member moves along the guide grooves.

說明書

The support member SM, the display panel DP, and the window WIN may be connected to the coupling portion CP, and the joint units JU may move toward the third guide member GM3 along the first extension portion EX1 according to the rotation of the first driving unit DU1. Accordingly, the display panel DP and the window WIN may move while being unrolled to allow the exposed area of the display panel DP and the window WIN to be expanded. The display panel DP and the window WIN may move along the first guide member GM1 and the second guide member GM2 toward the third guide member GM3.

In such an embodiment, when the first, second, and third driving units DU1, DU2, and DU3 rotate in the clockwise direction, the joint units JU may move to be disposed in the guide grooves GG as shown in FIG. 18. Accordingly, the display panel DP and the window WIN may be rolled on the second and third driving units DU2 and DU3, respectively, and the exposed area of the display panel DP and the window WIN may be reduced. The display panel DP and the window WIN may move along the first guide member GM1 and the second guide member GM2 to be farther away from the third guide member GM3.

Since the both sides of the joint units JU are inserted into the guide grooves GG and supported by the first and second guide members GM1 and GM2, the joint units JU may support the display panel DP, which is unrolled to enlarge the exposed area, to be substantially flat.
