  We study the pulsar energy-dependent $\gamma$-ray light curves and spectra
from curvature radiation in the dissipative magnetospheres. The dissipative
magnetospheres with the combined force-free (FFE) and Aristotelian (AE) are
computed by a pseudo-spectral method with the high-resolution simulation in the
rotating coordinate system, which produces a near force-free field structure
with the dissipative region only near the equatorial current sheet outside the
light cylinder (LC). We use the test particle trajectory method to compute the
energy-dependent $\gamma$-ray light curves, phase-average and phase-resolved
spectra by including both the accelerating electric field and radiation
reaction. The predicted energy-dependent $\gamma$-ray light curves and spectra
are then compared with those of the Vela pulsar observed by Fermi. Our results
can generally reproduce the observed trends of the energy-dependent
$\gamma$-ray light curves and spectra for the Vela pulsar.
