Abstract: PROBLEM TO BE SOLVED: To provide a display cell which is made lightweight by reducing the thickness of glass and can have enough strength needed for its manufacturing process. SOLUTION: Provided are a color filter substrate 10 which has an image display area and a TFT array substrate 20 which is arranged opposite to the color filter substrate 10 and has a frame edge part 24 positioned along its circumference and a recessed part 22 surrounded with the frame edge part 24. The frame edge part 24 of the TFT array substrate 20 is formed thicker than the recessed part 22. The color filter substrate 10 has a frame edge part 12 and a recessed part 11 surrounded with the frame edge part 12, and the frame edge part 12 is formed thicker than the recessed part 11. The thickness of the recessed part 11 or the thickness of the frame edge part 12 and the thickness of the recessed part 11 are made smaller than the thickness of the frame edge part 24 of the TFT array substrate 20.

Abstract: PROBLEM TO BE SOLVED: To reduce variation of plate thickness of a TFT glass substrate (an array substrate) after polishing.
SOLUTION: On a corner part 4 where an X-edge 2 and a Y-edge 3 of the TFT glass substrate 1 intersect each other, a C-chamfering 5 as a chamfer with a specified dimension from an intersection 4a of X-, Y-edges is provided and polishing is carried out while a CF substrate 11 is laminated. By providing the C-chamfering 5, a polishing layer of a lower surface plate 609 is brought into contact with a full surface of the TFT glass substrate 1 with a uniform load. Thereby, when the TFT glass substrate 1 is polished with a polishing device 600, deformation of the corner part 4 generated by making a seal part a fulcrum is diminished. As a result, reduction of polishing amount on a single plate part 1a is prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a liquid crystal display device by which the thickness of a single plate part of a glass substrate to which a liquid crystal driving driver is to be attached is made constant without variance, and connection of the liquid crystal driving driver is ensured. SOLUTION: In the method of manufacturing the liquid crystal display device by which a liquid crystal cell provided with a pair of glass substrates is polished into a thin product after working vertical and horizontal dimensions of the liquid crystal cell to a product size, a spacer member 5 is provided on one glass substrate 2 to which a liquid crystal driving driver 8 is to be attached, and a liquid crystal cell 10 is polished.
