Manufacturing method of liquid crystal display and liquid crystal display

The invention discloses a manufacturing method of a liquid crystal display. The method comprises the following steps: step 1, establishing an off state exiting spectrum-cell gap related model; step 2,calculating respectively corresponding first cell gap, second cell gap and third cell gap when reaching the needed R wave band off state exitance, G wave band off state exitance and B wave band off state exitance; step 3, manufacturing the needed liquid crystal display, wherein the needed liquid crystal display comprises the first cell gap at a R region, the second cell gap at a G region and thethird cell gap at a B region. The manufacturing method can control the needed liquid crystal display to simultaneously have the needed off state exitance on a red light wave band, a blue light wave band and a green light wave band, can improve off state effects of the liquid crystal display and realizes an aim of high contrast, high NTSC and low color cast. The invention also provides a liquid crystal display. 本发明公开了种液晶显示器
