  We discuss the asymmetry of cosmic background evolution in time with respect
to the quantum bounce in the Loop Quantum Cosmology (LQC), employing the value
of scalar field at the bounce $\phi_{\rm B}$. We use the Chaotic and the $R^2$
potentials to demonstrate that a possible deflation before the bounce may
counteract the inflation that is needed for resolving the cosmological
conundrums, so a certain level of time asymmetry is required for the models in
LQC. This $\phi_{\rm B}$ is model dependent and closely related to the amounts
of deflation and inflation, so we may use observations to confine $\phi_{\rm
B}$ and thus the model parameters. With further studies this formalism should
be useful in providing an observational testbed for the LQC models.
