A lighting structure of a liquid crystal panel in a gauge for a vehicle including: a dial having a pointer driving shaft insert hole and a scale corresponding to measured quantities arranged substantially in the form of a circular arc on the pointer driving shaft insert hole at a center; a pointer member having a pointer main body which includes a shaft connecting part fixed to an end of a pointer driving shaft and a pointer part extending in a radial direction of the dial from the shaft connecting part to indicate the scale, the pointer main body being formed with a light guide material illuminated by illuminating lights introduced to the pointer driving shaft; a liquid crystal display panel arranged with a prescribed distance spaced forward from a front end of the shaft connecting part so as to cover a front part of the shaft connecting part; a pointer driving part including the pointer driving shaft formed in the shape of a shaft with the light guide material and inserted into the pointer driving shaft insert hole, arranged in a back part of the dial and rotates and drives the pointer driving shaft in accordance with a measured value so that the pointer main body indicates the scale corresponding to the measured value; a pointer illuminating light source arranged in a back part of the pointer driving shaft and allowing the illuminating lights to be introduced to the pointer driving shaft so as to light the pointer main body; characterized by an illuminating light dividing and output part provided to protrude to the liquid crystal display panel side from the front end of the shaft connecting part and outputting a part of the illuminating lights received from the pointer driving shaft to the liquid crystal display panel side; and a luminance adjusting part provided between the illuminating light dividing and output part and the liquid crystal display panel to distribute the illuminating lights outputted by the illuminating light dividing and output part to all areas of the back surface of the liquid crystal display panel, so that a luminance of the liquid crystal display panel is adjusted by a part of the illuminating lights outputted by the pointer illuminating light source, wherein the luminance adjusting part includes a first luminance adjusting plate (71; 71A; 71B) arranged so as to be opposed to a front end surface of the illuminating light dividing and output part at a position spaced by a suitable distance from the front end of the illuminating light dividing and output part to the liquid crystal display panel side and a second luminance adjusting plate formed to protrude in the periphery of the front end of the shaft connecting part in the shape of a curved surface recessed to the liquid crystal display panel. a dial having a pointer driving shaft insert hole and a scale corresponding to measured quantities arranged substantially in the form of a circular arc on the pointer driving shaft insert hole at a center;
