A polyamic acid according to an embodiment is formed by a polymerization reaction of a dianhydride compound, a first diamine compound represented by the following Formula 1, and a second diamine compound, which is different from the first diamine compound. A polyimide film derived from the polyamic acid may exhibit excellent heat resistance and improved optical properties: 

Polyamic acid, polyimide film and fabrication method of the polyimide film

A display apparatus includes a base substrate, a thin film transistor disposed on the base substrate and including an active pattern, a gate electrode, a source electrode, and a drain electrode, an inorganic insulating layer disposed between the active pattern and the gate electrode, a first organic insulating layer disposed on the thin film transistor, a second organic insulating layer disposed on the first organic insulating layer, and an insulating layer disposed between the first organic insulating layer and the second organic insulating layer and in direct contact with the first organic insulating layer and the second organic insulating layer.

Display apparatus that protects internal elements from external shock

A display device includes a display panel including first and second expansion portions, and a center portion between the first and second expansion portions; a first outer frame connected to the first expansion portion; a second outer frame connected to the second expansion portion; an intermediate frame disposed between the first and second outer frames, and overlapping the center portion of the display panel; a first guide shaft on the intermediate frame; a first motor connected to the first guide shaft; a first slide connected to the first guide shaft and configured to move along the first guide shaft; a first connection portion rotatably connected to one side of the first slide and one end portion of the first outer frame; and a second connection portion rotatably connected to another side of the first slide and one end portion of the second outer frame.

Display device configured to transform between a contracted configuration and an expanded configuration

A display device includes: a display panel; a light source; and a light guide plate receiving light from the light source and providing the light to the display panel. The light guide plate includes an upper surface facing the display panel, a light incident surface facing the light source and a light opposing surface opposing the light incident surface. The upper surface includes a lens pattern and the lower surface incudes a prism pattern, the prism pattern includes a plurality of prisms arranged along a first direction from the light incident surface to the light opposing surface, each of the prisms has a length extending in a second direction along a length of the light incident surface, and among the prisms arranged along the first direction within the prism pattern, the lengths of the prisms increase as a distnace from the light incident surface increases.
