Abstract: A battery pack is disclosed. In one aspect the battery pack includes a battery cell including an electrode assembly and a pouch that seals the electrode assembly and a frame that accommodates the battery cell, wherein the frame comprises i) a main frame that surrounds the battery cell and ii) a rib that crosses the main frame. The pouch includes i) a pair of side-wing units each having a shape substantially similar to a side surface of the battery cell and extending in a direction and ii) a terrace unit connected to the side-wing units. Each of the side-wing units includes an extension unit that extends on the terrace unit along the direction. The frame includes an insertion unit into which the extension unit is inserted, and the rib is located on the terrace unit. According to embodiments, the capacity of the battery pack increases.

Abstract: A backlight unit having improved luminance and reduced profile, and a liquid crystal display including the same are disclosed. In one embodiment, the backlight unit includes: i) a light source, ii) a light guiding plate including an incoming surface on which light generated from the light source is incident, an upper surface substantially perpendicularly extended with respect to the incoming surface, and a bottom surface arranged facing the upper surface and iii) an optical sheet formed on the light guiding plate. The upper surface of the light guiding plate includes a guiding surface, an incoming surface, and an emission surface sequentially arranged close to the incoming surface of the light guiding plate, and the optical sheet may be formed to cover the inclined surface and the guiding surface.
