To suppress generation of black floating.SOLUTION: An image processing device includes: a maximum luminance setting part for associating a maximum luminance value contained in an area corresponding to a luminance image to each of a plurality of areas in which a display area of a second liquid crystal panel is classified into a plurality of areas so as to contain an overlapping area which is overlapped with a plurality of first pixels of a first liquid crystal panel per one pixel; an order setting part for setting the order in the plurality of areas in the descending order in terms of the maximum luminance value; and a transmittance setting part which sets transmittance of a focused pixel out of the plurality of first pixels in the order set in the overlapping area overlapped with the focus pixel based on the maximum luminance value associated with the overlapping area overlapped with the focused pixel. The transmittance setting part sets the transmittance of the focused pixel out of the plurality of first pixels overlapped with the overlapping area based on a transmittance coefficient that shows a ratio of each of the plurality of first pixels overlapped with the overlapping area having an impact of transmission light in the overlapping area.SELECTED DRAWING: Figure 18 【課題】黒浮きの発生を抑制する。【解決手段】１画素当たり第１液晶パネルの複数の第１画素と重なる重複エリアを含むように第２液晶パネルの表示エリアが複数に分類された複数のエリアのそれぞれに、輝度画像の対応するエリアに含まれる最大輝度値を対応付ける最大輝度設定部と、前記最大輝度値が大きい順に前記複数のエリアに順序を設定する順序設定部と、前記複数の第１画素のうち着目画素の前記透過率を、前記着目画素に重なる前記重複エリアに設定された前記順序で、前記着目画素に重なる前記重複エリアに対応付けられた前記最大輝度値に基づいて設定する透過率設定部と、を備え、前記透過率設定部は、前記重複エリアと重なる前記複数の第１画素のうち、前記着目画素の前記透過率を、前記重複エリアと重なる前記複数の第１画素のそれぞれが前記重複エリアに透過光の影響を与える割合を示す透過率係数に基づいて設定する。【選択図】図１８
