Explanation:

A thin-film transistor (TFT) is a type of field-effect transistor that is usually used in a liquid crystal display (LCD). This type of display features a TFT for each individual pixel. These TFTs act as individual switches that allow the pixels to change state rapidly, making them turn on and off much more quickly.
Thin film has a thickness in the order of 0.1 micrometer or smaller, while thick film is around thousands time thicker. However, the main difference is method the resistive film is applied onto the substrate. ... Thick film resistors are produced by firing a special paste onto the substrate.
