Problems solved by technology
Therefore, there is a problem that uniform polarization characteristics cannot be exhibited as a whole of the polarizing element.
In addition, there is a problem that when the temperature rises during the operation of the liquid crystal device, the polarization characteristics deteriorate due to the deterioration of the metal lattice.

Description
technical field [0001] The present invention relates to a polarizing element, a method for manufacturing the polarizing element, a liquid crystal device, and an electronic device. Background technique [0002] Liquid crystal devices are used as light modulation devices of various electro-optical devices. As a structure of a liquid crystal device, a structure in which a liquid crystal layer is sandwiched between a pair of opposing substrates is known. Also, a configuration including a polarizing element for injecting predetermined polarized light into the liquid crystal layer and an alignment film for controlling the alignment of liquid crystal molecules when no voltage is applied is common. [0003] As a polarizing element, there are known thin-film polarizing elements manufactured by stretching a resin film containing iodine and a dichroic dye in one direction to orient iodine and a dichroic dye in the stretching direction, and transparent substrates A wire-grid polarizin...
