Description

technical field [0001] The present invention relates to a method for manufacturing a liquid crystal device and a liquid crystal device. Background technique [0002] The liquid crystal device includes a liquid crystal cell in which a liquid crystal layer is sandwiched between a pair of opposed substrates, and a pair of polarizing plates arranged on both outer sides of the liquid crystal cell. Since the liquid crystal device performs display using polarized light, the alignment direction of the liquid crystal molecules in the liquid crystal layer and the optical axes of the pair of polarizing plates are set to form a predetermined positional relationship. Therefore, if the predetermined arrangement positions of the liquid crystal cell and the polarizing plate are shifted in the step of attaching the polarizing plate to the liquid crystal cell, desired optical characteristics (contrast, etc.) cannot be obtained, resulting in a decrease in display quality. [0003] Therefore, ...

Problems solved by technology

[0007] However, in the method described in the above-mentioned Patent Document 1, since the alignment mark and the outer shape of the polarizing plate are aligned, it is difficult to accurately align the polarizing plate with respect to the liquid crystal cell when the outer shape of the polarizing plate and the optical axis are misaligned. The problem of aligning the optical axis of the polarizing plate

In the method described in the above-mentioned patent document 2 and patent document 3, owing to the optical axis of the main polarizer is a reference, the alignment direction of the liquid crystal cell and the optical axis of each polarizing plate are independently aligned and pasted, so there are the following The problem is that the number of alignment and bonding processes increases man-hours, and if there is a shift in the position of the main polarizer, the shift will be reflected in the alignment of the liquid crystal cell and the polarizer
