1. A cassette for receiving mother substrates, the mother substrates including a plurality of liquid crystal display panels, each including liquid crystal, the cassette comprising: a frame, including: a top wall having a front edge, a rear edge, a left edge and a right edge;a right wall having a front edge, a rear edge, a top edge and a bottom edge,wherein the right edge of the top wall meets the top edge of the right wall; a bottom wall having a front edge, a rear edge, a left edge and a right edge,wherein the bottom edge of the right wall meets the right edge of the bottom wall; a left wall having a front edge, a rear edge, a top edge and a bottom edge, wherein the left edge of the bottom wall meets the bottom edge of the left wall, and wherein the top edge of the left wall meets the left edge of the top wall; anda rear wall having a top edge, a bottom edge, a left edge and a right edge, wherein the top, bottom, left and right edges of the rear wall meet the rear edges of the top, bottom, left and right walls, respectively, and wherein the front edges of the top, bottom, left and right walls define a plane forming an open front side of the frame;a plurality of substantially flat E-shaped support plates attached in the frame to support rectangular mother substrates having large liquid crystal display panels formed thereon by a liquid crystal dropping method to be placed thereon, each support plate having an overall length of the support plate that is greater than an overall width of the support plate, each support plate including: a left widthwise edge attached to the left wall of the frame;a right widthwise edge attached to the right wall of the frame;a rear lengthwise edge disposed adjacent to and spaced from the rear wall of the frame and extending in a straight line from the left widthwise edge to the right widthwise edge;a front lengthwise edge disposed adjacent to and spaced from the plane forming the open front side of the frame, wherein the front lengthwise edge extends in a straight line from the left widthwise edge to the right widthwise edge except for first and second elongated notches formed in the front lengthwise edge of the support plate in order to accommodate a robot arm that is used to place a rectangular mother substrate on the E-shaped surface of the support plate, wherein the first and second elongated notches extend from the front lengthwise edge towards the rear lengthwise edge in a linear manner to match contours of the robot arm with an operational moving margin,wherein the plurality of E-shaped support plates contact with the mother substrates in surface-to-surface to minimize deformation of the mother substrates and to disperse the weight of the mother substrates,wherein a rear portion of the support plate extends from the left wall to the right wall to uniformly distribute a weight of the mother substrates in a lengthwise direction, wherein the width of the rear portion of the support plate is less than a length of each elongated notch and greater than a width of each elongated notch,wherein the width of the rear portion of the support plate is greater than a distance between the rear lengthwise edge of the support plate and the rear wall of the frame and is greater than a distance between the front lengthwise edge of the support plate and the plane forming the open front side of the frame, andwherein a wall thickness of the top, bottom, left, right and rear walls is less than the distance between the rear lengthwise edge of the support plate and the rear wall of the frame and is less than the distance between the front lengthwise edge of the support plate and the plane forming the open front side of the frame.
