The front layer is made of liquid crystal diodes.
A
CRT
B
TFT
C
LCD
D
LED
Explanation: 

Detailed explanation-1: -The layer of liquid crystals is deposited on the inner surface of glass electrodes for the scattering of light. The liquid crystal cell is of two types; they are Transmittive Type and the Reflective Type.

Detailed explanation-2: -The heart of an LCD is a special liquid that is called a twisted nematic liquid crystal. This liquid has the capability of rotating the polarization of linearly polarized light.

Detailed explanation-3: -LCD (Liquid Crystal Display) is a type of flat panel display which uses liquid crystals in its primary form of operation. LEDs have a large and varying set of use cases for consumers and businesses, as they can be commonly found in smartphones, televisions, computer monitors and instrument panels.

Detailed explanation-4: -LCD (Liquid Crystal Display) For LCDs, two glass layers are separated by a thin liquid crystal layer (the ‘LC’ in LCD). This liquid crystal layer, in combination with other optical components, is responsible for creating the image by encoding the image in the orientation of the liquid crystal material.

Detailed explanation-5: -A liquid crystal display (LCD) has liquid crystal material sandwiched between two sheets of glass. Without any voltage applied between transparent electrodes, liquid crystal molecules are aligned in parallel with the glass surface.
