Embodiment Construction

[0017] Such as Figure 1 to Figure 2 As shown, a polarizer for an ultra-thin reflective liquid crystal display, which includes a release film layer 1, a pressure-sensitive adhesive layer 2, a polyvinyl alcohol (PVA) film layer 3, an adhesive layer 4, Reflective film layer 5. The above layers are compounded together by a compound machine.

[0018] The peeling film layer 1 is compounded on the upper surface of the polyvinyl alcohol (PVA) film layer 3 through the above-mentioned pressure-sensitive adhesive layer 2, and the reflective film layer 5 is compounded on the polyvinyl alcohol (PVA) film layer through the above-mentioned adhesive layer 4 The lower surface of layer 3.

[0019] The thickness of the pressure-sensitive adhesive layer 2 and the adhesive layer 4 can be appropriately set according to the intended use, adhesive strength and the like. Specifically, the preferable thickness is 1 μm to 100 μm, more preferably 5 μm to 50 μm, most preferably 10 μm to 30 μm.

Abstract

The invention discloses a polaroid for an ultrathin reflection-type liquid crystal display, comprising a stripping film layer, a pressure-sensitive adhesive layer, a polyvinyl alcohol (PVA) film layer, an adhesive layer and a reflecting film layer which are overlaid from top to bottom, wherein the stripping film layer is compounded on the upper surface of the PVA film layer by the pressure-sensitive adhesive layer, and the reflecting film layer is compounded on the lower surface of the PVA film layer by the adhesive layer. The function of the polaroid for an ultrathin reflection-type liquid crystal display of the invention can be realized by only compounding the PVA film layer and the reflecting film layer. The polaroid of the invention has thin thickness and is convenient to use.

Description

technical field [0001] The invention relates to a polarizer, in particular to a polarizer for an ultra-thin reflective liquid crystal display. [0002] Background technique [0003] The polarizer for ordinary reflective liquid crystal display is a kind of optical film with polarizing function compounded by multi-layer polymer materials. It is mainly used in the fields of liquid crystal displays such as calculators and game machines. [0004] Ordinary reflective liquid crystal display polarizers mainly have the following disadvantages: ordinary reflective liquid crystal display polarizers are traditional reflective polarizer structures: pressure-sensitive adhesive layer / triacetate cellulose (TAC) film layer / polyvinyl alcohol (PVA) film layer / triacetate cellulose (TAC) film layer / reflective film layer, a layer of triacetate cellulose (TAC) is compounded on both sides of the polyvinyl alcohol (PVA) film layer for protection and support, polarizer The overall thickness is thic...
