PROBLEM TO BE SOLVED: To display information related to a motor generator, in addition to information related to an engine, without size increase of a display device, cost increase and reduction of visibility of display information.SOLUTION: A display device for a work vehicle comprises: a liquid crystal display device 31 having plural display parts 31A-31F for displaying information related to an engine in segment display; and a display electronic control unit for controlling operation of the liquid crystal display device 31. The liquid crystal display device 31 comprises an auxiliary display part 31G for displaying information related to a motor generator on an empty region thereof. The auxiliary display part 31G comprises a display portion for four digits in 7 segment display. The display electronic control unit comprises a control part for the auxiliary display part which operates the display portion on a first digit of the auxiliary display part 31G, as a first display portion 31Ga for displaying a state of the motor generator by characters, and operates the residual display portion for three digits, as a second display portion 31Gb for displaying a residual quantity of a battery by numerical values.SELECTED DRAWING: Figure 5 【課題】表示装置の大型化、コストの上昇、表示情報の視認性の低下を招くことなく、エンジンに関する情報に加えてモータジェネレータに関する情報を表示できるようにする。【解決手段】作業車の表示装置は、エンジンに関する情報をセグメント表示する複数の表示部３１Ａ〜３１Ｆを有する液晶表示器３１と、液晶表示器３１の作動を制御する表示用電子制御ユニットとを備え、液晶表示器３１は、その空き領域に、モータジェネレータに関する情報を表示する補助表示部３１Ｇを備え、補助表示部３１Ｇは、７セグメント表示で４桁の表示部位を備え、表示用電子制御ユニットは、補助表示部３１Ｇの１桁目の表示部位を、モータジェネレータの状態を文字表示する第１表示部位３１Ｇａとして作動させ、かつ、残りの３桁の表示部位を、バッテリの残量を数値表示する第２表示部位３１Ｇｂとして作動させる補助表示部用の制御部を備えている。【選択図】図５
