We present $H$- and $K_{\rm s}$-bands observations of the LkH$\alpha$ 330disk with a multi-band detection of the large gap and spiral-like structures.The morphology of the outer disk ($r\sim$$0\farcs3$) at PA=0--45$^\circ$ andPA=180--290$^\circ$ are likely density wave-induced spirals and comparisonbetween our observational results and simulations suggests a planet formation.We have also investigated the azimuthal profiles at the ring and the outer-diskregions as well as radial profiles in the directions of the spiral-likestructures and semi-major axis. Azimuthal analysis shows a large variety inwavelength and implies that the disk has non-axisymmetric dust distributions.The radial profiles in the major-axis direction (PA=$271^\circ$) suggest thatthe outer region ($r\geq0\farcs25$) may be influenced by shadows of the innerregion of the disk. The spiral-like directions (PA=10$^\circ$ and 230$^\circ$)show different radial profiles, which suggests that the surfaces of thespiral-like structures are highly flared and/or have different dust properties.Finally, a color-map of the disk shows a lack of an outer eastern region in the$H$-band disk, which may hint the presence of an inner object that casts adirectional shadow onto the disk.
