PROBLEM TO BE SOLVED: To provide a work vehicle which allows an operator to easily grasp a point where a target travel route is deviated from an actual travel locus.SOLUTION: The work vehicle comprises: a display 51 capable of displaying a target travel route on a work place W; an index value calculation device for calculating an index value which indicates a degree of deviation of an actual travel locus to the target travel route; and a color-coding processing device for performing color-coding, according to the index value, on a part where travel is completed of the target travel route displayed on the display 51.SELECTED DRAWING: Figure 10【課題】目標走行経路と実際の走行軌跡とがずれた地点をオペレータが把握し易い作業車を提供する。【解決手段】作業地Wにおける目標走行経路を表示可能なディスプレイ51と、目標走行経路に対する実際の走行軌跡のずれの程度を示す指標値を算出する指標値算出装置と、ディスプレイ51に表示される目標走行経路のうち、走行が完了した部分を、指標値に応じて色分けする色分け処理装置と、を備える。【選択図】図10
