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

Abstract

The present invention provides a liquid crystal device manufacturing method for reducing the position deviation of an optical shaft of a liquid crystal unit and an optical shaft of a polarization optical plate and a liquid crystal device. The liquid crystal device manufacturing method includes: a working procedure for preparing the liquid crystal unit having a liquid crystal layer clamped between an element substrate and a contraposition substrate which are opposite to each other, at least one position arranged at the element substrate, and a wire grating polariscope with polarized light separating function; a first working procedure, under the state of contraposition of a polarized light plate with the outer side of the element substrate of the liquid crystal unit, at least one of the liquid crystal unit and the polarized light plate rotates in the contraposition surface, for detecting the intensity of light which passes through a region arranged with wire grating polariscope of the liquid crystal unit and the polarized light plate; and a second working procedure, according to the detection result of the intensity of the light, for determining the position relationship of the polarized light plate relative to the wire grating polariscope in the opposite surfaces, and adhering the polarized light plate on the element substrate of the liquid crystal unit.

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, ...
