Patent ID: 8082858

Claim:
A display substrate accommodating tray, comprising: a bottom section supports a display substrate on at least a portion of a planar top surface of the bottom section, wherein the portion of the planar top surface supporting the display substrate has a surface area that is at least the majority of the surface area of the bottom surface of the display substrate; a frame provided along a periphery of the bottom section, the frame projecting to a level higher than a level of the top surface of the bottom section; and a flange-like engaging section, protruding externally from walls of said frame in a substantially horizontal fashion such that a horizontal gap extending to an outer periphery of the display substrate accommodating tray is provided below the flange-like engaging section, to be engaged by a carrying section moving from outside the periphery horizontally into the horizontal gap for carrying the display substrate accommodating tray; wherein a planar top surface of the frame and a wall defining an inner periphery of the flange-like engaging section define a positional relationship between the display substrate accommodating tray and another display substrate accommodating tray which is to be stacked thereon, wherein the planar top surface of said frame is parallel to the planar top surface of the bottom section having the display substrate and the wall of the flange-like engaging section is connected to said planar surface of said frame, wherein the wall of the flange-like engaging section projects to a level higher than the level of the planar top surface of the frame with respect to the surface of the bottom section, and the width of the frame is substantially larger than the distance between the top of the top surface of the frame and the top surface of the bottom section.
