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.
