Motivated by the 3.8 sigma deviation from no CP violation hypothesis for the CP asymmetry (CPA) difference between D-0 -> K+K- and D-0 -> pi(+)pi(-), reported recently by LHCb and CDF, we investigate the CP violating effect due to the left-right (LR) mixing in the general LR symmetric model. In particular, we show that the large CPA difference could be explained in the non-manifest LR model.
