Abstract: A display device includes: a display panel and a protective member disposed on the display panel. The protective member includes: a window disposed on the display panel; a protective layer disposed on the window; a first protective adhesive layer disposed between the window and the protective layer, and a second protective adhesive layer disposed between the display panel and the window. The first protective adhesive layer has a storage modulus of about 2 MPa to about 8 MPa at frequencies of about 20,000 Hz to about 100,000 Hz and a temperature of about 25° C. The second protective adhesive layer has a first loss factor of about 1.6 to about 2.5 at frequencies of about 20,000 Hz to about 100,000 Hz and a temperature of about 25° C.
