Abstract

The invention discloses a polarizing plate, a display panel and a production method thereof. The display panel comprises a liquid crystal box, a liquid crystal layer and the polarizing plate, wherein the liquid crystal box comprises a first substrate and a second substrate opposite to the first substrate, and the liquid crystal layer is arranged between the first substrate and the second substrate; the polarizing plate is arranged on one side, far away from the liquid crystal layer, of the first substrate and / or the second substrate; and the polarizing plate comprises a polarizing photon layer and a first glass substrate, the polarizing photon layer is arranged on the side, away from the liquid crystal layer, of the first substrate and / or the second substrate, and the first glass substrate is arranged on the side, away from the liquid crystal box, of the polarizing photon layer. The first glass substrate is used as a protective layer of the polarizing photon layer and has the effect of isolating water vapor, damage of the water vapor to the polarizing plate is avoided, and then the display defects such as light leakage or uneven display of the display panel are overcome.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a polarizer, a display panel and a preparation method thereof. Background technique [0002] The polarizers used in display devices such as liquid crystal displays (Liquid Crystal Display, LCD) and organic light emitting diodes (Organic Light Emitting Diode, OLED) usually have a multifunctional layer structure, such as figure 1 as shown, figure 1 It is a structural schematic diagram of a polarizing plate in the prior art. The polarizing plate 10 includes a polarizing sub-layer 11 with a polarizing effect, and the material of the polarizing sub-layer 11 can be a polyvinyl alcohol film layer (Polyvinyl Alcohol, PVA) etc.; Layer 12 and the second protective layer 13, the material of the first protective layer 12 and the second protective layer 13 can be Tri-cellulose Acetate (Tri-cellulose Acetate, TAC), ethylene glycol phthalate (PolyethyleneGlycol Terephthalate, PET ...
