Claim:
1. A vehicular display apparatus comprising: a first light source and a second light source; a display plate including a liquid crystal display unit to provide a liquid crystal display using the first light diffused by the diffusion portion as back light, the display plate including a light shielding wall to provide a partition between a first light path from the first light source to the diffusion portion and a second light path from the second light source to each of the transmission display portions, the light shielding wall including a convex portion that is inserted into the slit; and a circuit board to which the first light source and the second light source are mounted; wherein: the plurality of transmission display portions are a first transmission display portion and a second transmission display portion; the first transmission display portion and the second transmission display portion are arranged to be adjacent to each other via a predetermined intervening region in the display plate; the diffusion portion includes (i) a convexly intervening sub-portion and (ii) a different sub-portion from which the convexly intervening sub-portion is protruding, the convexly intervening sub-portion corresponding to the predetermined intervening region so that the convexly intervening sub-portion of the diffusion portion is sandwiched between the first transmission display portion and the second transmission display portion; the slit is formed as each of a first slit corresponding to the first transmission display portion and a second slit corresponding to the second transmission display portion, wherein the convexly intervening sub-portion of the diffusion portion is sandwiched between the first slit and the second slit; while the convexly intervening sub-portion protruding from the different sub-portion is provided as reaching a peripheral end of the display plate to separate the first transmission display portion and the second transmission display portion from each other; the first slit is formed in a first border portion, the first slit having a first length and two first ends of the first length, the first length being formed to be extended along the first border portion, the second slit is formed in a second border portion, the second slit having a second length and two second ends of the second length, the second length being formed to be extended along the second border portion, the display plate is arranged to face the circuit board; each of the transmission display portions faces the second light source and displays a prescribed shape formed by the prescribed shape portion contained in each of the transmission display portions by transmitting the second light from the second light source through the prescribed shape portion; and the diffusion portion faces the first light source and transmits and diffuses the first light from the first light source while propagating the first light through an internal portion of the diffusion portion, the first light propagated through the internal portion of the diffusion portion being prevented from leaking to each of the transmission display portions by the slit.
