1. A lamp for a vehicle comprising:
a light source part configured to generate and output light in a first direction defining a first optical axis; and
a lens array provided on a front side of the light source part, the lens array comprising:
a first lens part comprising a first light transmitting body, a plurality of first micro lenses on a surface of the first light transmitting body facing the light source part such that the light is input from the light source part, the first light transmitting body configured to transmit the input light;
a second lens part comprising a second light transmitting body facing the first light transmitting body, a plurality of second micro lenses on a surface of the first light transmitting body facing an opposite direction to the direction that faces the first light transmitting body, the plurality of second micro lenses configured to output the light input from the first lens part in a second direction defining a second optical axis, and form a specific beam pattern; and
a shield part located between the first lens part and the second lens part, and configured to shield a portion of the light input from the first lens part toward the second lens part to form a specific beam pattern on the road surface,
wherein the second optical axis is inclined with respect to the first optical axis such that, when installed in a vehicle, the lens array faces a road surface,
wherein the second lens part is disposed to become closer to the light source part as they go toward the lower side of the lens array such that the second optical axis forms a specific angle with respect to the first optical axis, and
wherein the shield part comprises a plurality of unit masks that correspond to the plurality of second micro lenses, and in which masking patterns for forming the beam pattern are formed, and the plurality of unit masks are disposed to become farther from the second micro lenses as they go to a lower side of the lens array.
