is my monitor screen plastic?

LCD monitor  breaks the picture down into dots and recreates it. However, it works by shining light through two sheets (usually plastic) with a layer of liquid crystal between them. The sheets are polarized in a perpendicular manner, meaning that the light which passes through the inside sheet cannot pass through the outside sheet without manipulation. This manipulation comes from the individual crystals which, in response to an electrical charge, can change the direction of the light passing through and, in turn, cause it to pass through the outside sheet and become visible. The actual outside of the monitor can be glass or plastic and is simply a transparent protective layer to prevent damage to the polarized sheets. An LED screen is simply a version of an LCD screen that uses LEDs to shine the light through the polarized sheets and crystals.

no, your monitor have a specific screen but not plastic
