Liquid crystal displays are flat panel monitors which modify a white backlight by creating a barrier of millions of liquid crystals which can adjust which color is ultimately displayed to the end user. They have all but replaced the old CRT technology because of the significantly lower power usage and size reduction that they provide.
LCD monitors are polarized devices, meaning there is a screen in place that only allows the EM waves of light to pass at one angle only. This can be seen when you attempt to view a computer screen with polarized sunglasses. The purpose of this polarization is to allow the orientation of the liquid crystal molecules to determine if light passes through them or not, which forms the basic structure of the monitor.
Every LCD has a system of pixels, and within those pixels is a sub pixel structure that consists of three color filters—red, green, and blue. By passing light through these colors in either on or off states, the appearance of every color the human eye can process can be created. The on-off states are controlled by applied voltages through selector transistors in the display. These are TFT transistors, which actually are not transparent, but they are small enough that it does not significantly affect the light available for the monitor and are not noticeable to the human eye
