When the thickness of a filter layer 170 in a light-reflecting portion R (the thickness of a thin portion 170a) is 'FR', the thickness of the filter layer 170 in a light-transmitting portion T (the thickness of a thick portion 170b) is 'FT', the thickness of a liquid crystal layer 150 in the light-reflecting portion R is 'LR', the thickness of the liquid crystal layer 150 in the light-transmitting portion T is 'LT', and the depth of a groove 155 is 'D', the depth D of the groove 155 formed in a resin layer 160 is formed to satisfy the formula D=(LT-LR)+(FT-FR). With defining (LT-LR) as 'L' and (FT-FR) as 'F', the formula becomes D=L+F. If the depth of the groove 155 satisfies the formula, it is possible to make an optical path length of external light N equal to an optical path length of illumination light B from a backlight 200 when they pass through the liquid crystal panel.
