Abstract

PURPOSE:To decrease surface reflection and to improve image grade by forming a magnesium fluoride layer on one or both surfaces of a polarizing plate. CONSTITUTION:The magnesium fluoride layer 4 is formed by a vacuum deposition method on one or both surfaces of the polarizing plate 1 formed by interposing a polarizing element between two sheets of bases 2 each made of a triacetyl cellulose film. The surface reflection is decreased and the easily visible display is obtd. by the presence of such magnesium layer 4 and since the surface is not subjected to roughening for the purpose of preventing dazzle, the image having the high grade is obtd. without the loss of the resolution.

[Prior Art] Conventionally, polarizing plates have been made by coating both sides of the polarizing element with cellulose-based films or These polarizing plates are reinforced and supported by a transparent resin layer such as acrylic, p-urethane, or epoxy. Because there is a lot of reflected light, the display is grainy and difficult to view.

７ツ化マグネＶウム層（４）を形成している。Conventional anti-glare processing includes, for example, roughening the surface of the support layer.[This invention is yet to be solved] However, with this anti-glare processing, the resolution of the displayed image decreases and blurring occurs. [Means for solving the problem] The purpose of the present invention is to eliminate these drawbacks, and the gist thereof is to There is a polarizing plate characterized in that a magnesium heptafluoride layer is immediately formed. [Function] The surface reflection is optically reduced by the magnesium heptafluoride layer. [Example] Section 1.2 The figure shows a preferred embodiment of the present invention, in which (1) is a polarizing plate, which is formed by interposing a polarizing element (3) between two supports (2) made of triacetyl cellulose film. ◎ A desired amount of a magnesium Vium heptadide layer (4) is formed on one side of this polarizing plate (1) by vacuum evaporation.
