The low heavy metal and heavy metal free QDs (Cd < 100 ppm, Pb‐free) content of the R, G, B‐QDs was deposited on top of the conventional twist nematic (TN) liquid crystal device to improve the viewing angle of liquid crystal display. The non‐vacuum, low materials consumption solution process by aerosol‐jet deposition has the advantage of direct printing on black matrix pattern glass. The intensity of 410 nm was applied to execite the QD film and was modulated by the TN cell. As a result, the LC retardation and response time can be fully optimized within the small cell gap. In particular, the eco‐QD array TNLCD possesses wide viewing angle, high transmittance, and fast response time (< 3 ms) under low driving voltage (4 V).
