A vehicle lamp, comprising: a light source unit comprising at least one light source configured to generate light; a lens that is arranged closer to a front of the vehicle lamp as compared to the light source unit, the lens configured to transmit the light generated by the light source unit; a shield that is arranged between the light source unit and the lens, and configured to receive the light generated by the light source and allow at least a portion of the received light to pass therethrough; and at least one processor configured to control a light transmittance of the shield, wherein the shield comprises a plurality of pixels having respective light transmittances that are configured to be variably controlled, and wherein each of the plurality of pixels is configured to allow independent control of respective light transmittances, characterized in that the at least one processor is further configured to control a portion of the plurality of pixels of the shield to selectively block light from passing therethrough based on a presence or absence of a reflector in the light source unit to form a low beam having a cut-off line, when the reflector is present in the light source unit, the at least one processor controls the light transmittance of pixels included in a first portion corresponding to a lower end portion of the plurality of pixels to block light from passing through the first portion, and when the reflector is not present in the light source unit, the at least one processor controls the light transmittance of pixels included in a second portion corresponding to an upper end portion of the plurality of pixels to block light from passing through the second portion. a light source unit comprising at least one light source configured to generate light; a lens that is arranged closer to a front of the vehicle lamp as compared to the light source unit, the lens configured to transmit the light generated by the light source unit; a shield that is arranged between the light source unit and the lens, and configured to receive the light generated by the light source and allow at least a portion of the received light to pass therethrough; and at least one processor configured to control a light transmittance of the shield, wherein the shield comprises a plurality of pixels having respective light transmittances that are configured to be variably controlled, and wherein each of the plurality of pixels is configured to allow independent control of respective light transmittances, characterized in that the at least one processor is further configured to control a portion of the plurality of pixels of the shield to selectively block light from passing therethrough based on a presence or absence of a reflector in the light source unit to form a low beam having a cut-off line, when the reflector is present in the light source unit, the at least one processor controls the light transmittance of pixels included in a first portion corresponding to a lower end portion of the plurality of pixels to block light from passing through the first portion, and when the reflector is not present in the light source unit, the at least one processor controls the light transmittance of pixels included in a second portion corresponding to an upper end portion of the plurality of pixels to block light from passing through the second portion.
