Definitions

  • the oxypropylene structure represented by SP1 is preferably a group represented by *--(CH(CH 3 )--CH 2 O) n2 --* because the degree of orientation of the dichroic substance is higher.
  • n2 represents an integer of 1 to 3
  • * represents the bonding position with L1 or M1.
  • the polysiloxane structure represented by SP1 is preferably a group represented by *-(Si(CH 3 ) 2 -O) n3 -* because the degree of orientation of the dichroic substance is higher.
  • n3 represents an integer of 6 to 10
  • * represents the bonding position with L1 or M1.
  • the support to which the polarizer-forming composition is applied is not particularly limited.
  • the support will be detailed later.
  • the support may have an orientation layer on its surface.
  • Methods for forming an alignment film include, for example, rubbing treatment of the film surface of an organic compound (preferably polymer), oblique vapor deposition of an inorganic compound, formation of a layer having microgrooves, and the Langmuir-Blodgett method (LB film ) with organic compounds such as ⁇ -tricosanoic acid, dioctadecylmethylammonium chloride, and methyl stearate.
  • LB film Langmuir-Blodgett method
  • organic compounds such as ⁇ -tricosanoic acid, dioctadecylmethylammonium chloride, and methyl stearate.
  • As the alignment layer an alignment film formed by rubbing treatment or a photo-alignment film formed by light irradiation is preferable.
  • the image display device produced was evaluated as follows. [Deterioration of display performance] The produced image display device was placed in a constant temperature bath with a temperature of 85° C. and a humidity of 85%, and held for 100 hours. After taking it out of the constant temperature bath, the image display device was turned on, and the gap between the image display portions was observed from a distance of 50 cm to evaluate the deterioration of the display performance in the gap.
  • B Clearly visible gaps with brighter gaps than other areas
