Abstract: A deposition apparatus includes a plate; electrostatic chucks including a first surface on which the plate is disposed; and a second surface on which a substrate is supported; and a control device that controls a flatness between the electrostatic chucks, and each of the electrostatic chucks includes driving shafts disposed through an area of an edge of the first surface of each of the electrostatic chucks, and the control device controls the flatness between the electrostatic chucks through the driving shafts by measuring a height deviation between the electrostatic chucks.

Abstract: A polarizing plate and a display device including the same are provided. A polarizing plate includes a polarizer comprising an absorption axis and a transmission axis that intersect each other, a first retardation layer disposed on a surface of the polarizer, and a second retardation layer disposed on another surface opposite to the surface of the polarizer. An in-plane retardation value of the second retardation layer is greater than about 20 nm and less than about 100 nm. An angle between the absorption axis of the polarizer and a retardation axis of the second retardation layer is in a range of about 10° to about 45°.
