Abstract: The present disclosure discloses a liquid crystal display (LCD) panel and a display device. Two thin film transistors (TFT) are disposed in a sub-pixel of the LCD panel. A quantity of the TFTs is reduced, and an aperture ratio of the pixel is increased. A third capacitor is connected in series between a TFT in a sub-area and a liquid crystal capacitor in the sub-area. A voltage of the sub-area declines with an increase in capacitors. Therefore, a deflection angle of liquid crystal molecules in a main area is greater than a deflection angle of liquid crystal molecules in the sub-area, forming different viewing angles. In this way, a color shift is resolved.
