  • Patent number: 11892669
    Abstract: A polarizing plate and a display device including the same. The polarizing plate includes a retardation layer exhibiting ultraviolet blocking characteristics even in a state where the retardation layer does not include any ultraviolet absorber or light stabilizer. The polarizing plate can be used alone or in combination with an appropriate sunscreen or a light stabilizer as needed to selectively block ultraviolet rays in a region requiring blocking, without affecting display performance, such as color senses and image quality, of a display device. The polarizing plate can also be formed with a small thickness without requiring a separate ultraviolet blocking layer, and also has excellent durability, because the polarizing plate exhibits a certain ultraviolet blocking property even in the absence of an ultraviolet absorber or light stabilizer.

  • Patent number: 11822182
    Abstract: A method of vapor depositing a silane chemical onto a wire grid polarizer can include introducing a silane chemical and water into a chamber where the wire grid polarizer is located. The silane chemical and the water can be in a gaseous phase in the chamber. The silane chemical and the water can be maintained simultaneously in the gaseous phase in the chamber for period of time. The silane chemical and the water can react to form a (R1)2Si(OH)2 molecule, where each R1 is independently any chemical element or group. A silane coating can be formed on the wire grid polarizer from a chemical reaction of the (R1)2Si(OH)2 molecule with the wire grid polarizer and with other (R1)2Si(OH)2 molecules. The silane coating can be relatively thick and multi-layer. A thicker or multi-layer silane coating can have improved high temperature resistance relative to a thinner or mono-layer silane coating.
