The dishwasher includes a rack assembly having a plurality of dish holders into which dishes may be inserted and by which the dishes supported are separated from each other on the rack assembly. The plurality of dish holders includes first and second dish holders having different heights disposed adjacent to one another.

Abstract: A dishwasher is provided in which heights of basket(s) of a rack assembly may be easily changed. The dishwasher may include a frame configured to be inserted into and withdraw from a washing tub and plurality of basket positioning device configured to receive and support basket(s) at different heights.

Abstract: A display apparatus includes a display panel; a light source unit including a plurality of first point light sources and a plurality of second point light sources, wherein the point light sources supply light to the display panel; an optical film including a plurality of openings, wherein each opening exposes a first point light source, and is provided between the display panel and the light source unit at a distance from the light source unit; and a light source driver which supplies a driving power to the first point light sources if a three-dimensional image is displayed on the display panel, and supplies the driving power to the second point light sources if a two-dimensional image is displayed on the display panel.

Abstract: A dishwasher is disclosed which includes a rack disposed inside a washing cabinet, a rack and at least one shelf which is rotatably connected to the rack so as to be rotated to a raised upright position and then to a lowered upright position and held, and which is rotatable to the raised upright position and then rotated to a substantially laid down position. Space utilization is increased as a height of the shelf extending above the shelf is reduced and a size of another rack assembly which may be positioned above the rack assembly may be increased.

Abstract: A dishwasher is disclosed which includes a rack arranged inside of a washing cabinet, a plurality of shelves arranged on the rack, and a shelf holder installed on the tack. The shelf holder may include a plurality of shelf fixing parts that fix the shelves together. The dishwasher so configured is capable of minimizing the number of shelf holders needed to fix a plurality of shelves to a rack and, therefore, simplifies the assembly process.

Abstract: A dishwasher is disclosed which includes a washing cabinet, a frame disposed within the washing cabinet, and a basket, which is placed on the frame, and whose height is adjustable by a back and forth movement. With this construction, there is no need to lift the basket, rotate it 90°, and reposition the basket to adjust a height of the basket. Rather, it is possible to adjust the height of the basket by a simple operation of pulling the basket forward or pushing it rearward.
