Abstract: A display device which includes a display panel and a protection member above the display panel. The protection member may include an adhesive layer above the display panel, a first protection layer above the adhesive layer, and a second protection layer between the first protection layer and the adhesive layer.
The first protection layer may have a first thickness and a first modulus, and the second protection layer may have a second thickness less than the first thickness and a second modulus less than the first modulus. The minimum value of the second thickness may be 20 μm, and the maximum value of the second thickness may satisfy T2max=(0.13×T1−8.25)×ln M2+0.68×T1−5.1  (1)

Abstract: A protection film for an electronic device includes an adhesive layer including a first surface to which an electronic device is attached, and a film layer which contacts a second surface of the adhesive layer and includes at least one member, where a thickness of the adhesive layer satisfies Inequality 1:

z≤(5.1x+57.4)·ln(y)−(14.7x+140.5),



where z is the thickness of the adhesive layer in terms of micrometers, x is a modulus of a member of the film layer which directly contacts the adhesive layer in terms of gigapascals, and y is a total thickness of the film layer in terms of micrometers.
