Abstract: A flexible display device including a hard coating layer, the hard coating layer containing first hard coating oligomers, second hard coating oligomers having greater molecular weights than the first hard coating oligomers, a cross-linker, and a photoinitiator. The first hard coating oligomers may maintain the hardness of the hard coating layer and the second hard coating oligomers may improve the flexibility of the hard coating layer, such that damage to the hard coating layer may be prevented or reduced even when the flexible display device is bent.

Abstract: A display device includes a first pixel row, a first first-structure transmission line, a first second-structure transmission line, a first transistor, and a second transistor. The first pixel row includes a first first-color sub-pixel and a second first-color sub-pixel both for displaying a first color. The first second-structure transmission line neighbors the first first-structure transmission line with no intervening transmission line analogous to the first first-structure transmission line or the first second-structure transmission line being disposed between the first first-structure transmission line and the first second-structure transmission line. The first transistor is electrically connected through the first first-structure transmission line to the first first-color sub-pixel and receives a first test voltage. The second transistor is electrically connected through the first second-structure transmission line to the second first-color sub-pixel and receives a second test voltage different from the first test voltage.

Abstract: A flexible display device includes a flexible display panel and a window member. The flexible display device includes a folding area and a peripheral area disposed adjacent to the folding area. The window member includes at least first and second base layers. The second base layer is overlapped with the first base layer and has a modulus of elasticity that is higher than that of the first base layer. A thickness of a first portion of the first base layer, which is overlapped with the folding area, is greater than a thickness of a second portion of the first base layer, which is overlapped with the peripheral area.

Abstract: A flexible display device includes a flexible display panel and a window member. The flexible display panel includes a folding area, and a peripheral area disposed adjacent to the folding area. The window member includes a first base layer on the flexible display panel, and a second base layer having a substantially same modulus as that of the first base layer. A first thickness portion of the second base layer, which overlaps the folding area, has a thickness smaller than a thickness of a second thickness portion of the second base layer, which overlaps the peripheral area.

Abstract: A window member according to an embodiment of the inventive concept includes a first base member having a first thickness, a first impact absorbing layer disposed on one surface of the first base member and having a storage modulus less than that of the first base member and a second thickness, a first hard coating layer disposed on the first impact absorbing layer, and a second hard coating layer disposed on the other surface that is opposite to the one surface of the first base member. Here, a ratio of the second thickness to the first thickness is equal to or greater than about 1.0 and equal to or less than about 1.67. The first base member is bent with respect to a bending axis extending in one direction.
