Abstract: The present disclosure provides a display device with a display panel, an input sensing unit, and a protective member. The input sensing unit is disposed on the display panel. The protective member includes an insulating material and is disposed on the input sensing unit. The protective member includes a first protective portion and a second protective portion disposed on the first protective portion, where a first modulus of the first protective portion is greater than a second modulus of the second protective portion. The second protective portion with the lower modulus absorbs external impacts, and the first protective portion with the higher modulus disperses the absorbed impact and prevents the display panel from being deformed by an external force. Therefore, the impact resistance of the display device is improved.

Abstract: A display device may include a first transistor, a first electrode, a second electrode, a first intermediate layer, and a first changeable layer. The first electrode is electrically connected to the first transistor. The second electrode overlaps the first electrode. The first intermediate layer is positioned between the first electrode and the second electrode and may emit first light when the first electrode and the second electrode generate a first electric field. The first changeable layer, which overlaps the first electrode, may have a first transmittance value when the first electrode and the second electrode generate the first electric field, and may have a second transmittance value when the first electrode and the second electrode do not generate the first electric field. The second transmittance value is unequal to the first transmittance value.

The gate line extends along a first direction on the substrate and is connected to the thin film transistor. The color filter is disposed on the substrate. The roof layer is disposed on the color filter and is configured to define a tunnel-shaped cavity between the roof layer and the color filter. The tunnel-shaped cavity extends along a second direction crossing the first direction. A cross-sectional thickness of an area of the roof layer adjacent to the gate lines is smaller than a cross-sectional thickness of another area of the roof layer spaced apart from the gate lines.
