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 mask assembly includes a mask and a blocking stick. The mask includes a pattern region formed therein with openings and extends in a first direction. The blocking stick is disposed under the mask and overlaps a first side portion of the mask. The mask further includes dummy opening regions and opening regions. The dummy opening regions are arranged in the first direction in the first side portion of the mask, and are formed therein with openings. The opening regions are arranged in the first direction in a second side portion which is opposite to the first side portion of the mask and correspond to the dummy opening regions, respectively. The number of the openings per a unit area in each of the dummy opening region and the opening region is smaller than the number of the openings per a unit area in the pattern region.
