Why does the LCD panel of my monitor have defective pixels (Black, Red, Blue, Green and White)?

An LCD panel consists of numerous pixels. Some of the pixels may not operate properly, They are referred to as defective pixels or missing dots. It is difficult to manufacture a panel with zero defects using current LCD panel manufacturing technology. These defective pixels are not symptoms of an LCD malfunction or an initial failure. The defective pixels are usually classified into four types;white spots, bright spots, black spots and dark spots.
