Abstract

PURPOSE:To obtain a flexible liq. crystal display element suitable for attachment to a curved body by pressurizing and heating a pair of film substrates with a press having curved surfaces after sealing a liq. crystal in the gap betwen the substrates. CONSTITUTION:Electrodes are formed on two plastic film substrates 2, 2', orienting films are formed on the electrodes, and a sealant and an electrode transition material are printed. Granular spacers 3 are then spread all over the substrates 2, 2'. The substrates 2, 2' are brought into contact with the curved surfaces of pressing jigs 4, 4' by evacuation, and they are pressurized and heated to obtain a flexible liq. crystal display element having a curved surface. The curved surfaces of the jigs 4, 4' have such high accuracy in curvature by surface working that the curved surfaces coincide with each other in a contact state.

To manufacture a flexible liquid crystal display element constructed using the above method, a gap is formed between a pair of flat film substrates with electrodes formed on the inner surface using a sealing material via a granular spacer, and a liquid crystal is sealed in the gap. It was done. Therefore, when the element is completed, it has a flat shape, and when the element is installed in a curved installation body, the desired curved shape is obtained by bending the flat element.

示品位の低下は免れ得ない。However, in the above method, it is necessary to create a flexible liquid crystal display element in advance into a flat shape and then bend the flexible liquid crystal display element. However, as shown in FIG. 1, the flat element 1 (FIG. 1(a)) is curved to create a curved element 1.
' (FIG. 1(b)), the substrate tucks due to the difference between the inner diameter and outer diameter of the curved portion or due to local pressure, and the cell thickness of the device becomes non-uniform. For this reason, deterioration in display quality is inevitable.
