摘要： A foldable display device includes a window. The window includes a first sub window, a second sub window, and an adhesive layer for coupling the first sub window and the second sub window to each other. The first sub window includes a first base layer having light transmittance of 90% or more and a first anti-fingerprint layer disposed on an upper surface of the first base layer, and the second sub window includes a second base layer disposed on the first sub window. A contact angle of a folding area of an upper surface of the first sub window is less than a contact angle of a peripheral area of the upper surface of the first sub window.

摘要： An impact test apparatus includes a base plate having an upper surface on which a specimen is placed, a collision member that collides with the specimen, a dropping unit that drops the collision member from an upper area of the specimen to the specimen and adjusts a height that the collision member drops, a velocity measurement unit that measures a collision velocity of the collision member when the collision member collides with the specimen, and an evaluation unit that produces a representative value that is a collision velocity at which a probability of breakage of the specimen is about 50%, and evaluates an impact resistance of the specimen based on the representative value.

摘要： A foldable display device is capable of improving a strength of a folding area and substantially reducing or minimizing a dead space of a non-folding area. The foldable display device includes: a display panel including a folding area and a non-folding area, and having a front surface and a back surface that are opposite each other; a window adjacent the front surface of the display panel; an auxiliary layer adjacent the back surface of the display panel; a first adhesive layer between the display panel and the window; and a second adhesive layer between the display panel and the auxiliary layer. A width of the window at the folding area is greater than a width of the window at the non-folding area.

摘要： A window includes a substrate including a folding portion foldable with respect to a folding axis extending in a first direction. A plurality of groove patterns are defined in the folding portion. The folding portion includes a center portion and an outer portion, and the plurality of groove patterns include a first groove pattern disposed in the center portion and a second groove pattern disposed in the outer portion. The first groove pattern includes a first upper groove pattern and a first lower groove pattern, and the second groove pattern includes a second upper groove pattern and a second lower groove pattern. The first upper groove pattern and the first lower groove pattern partially overlap in the second direction, and the second upper groove pattern and the second lower groove pattern do not overlap in the second direction.
