IMAGE DISPLAY DEVICE AND LIQUID CRYSTAL LENS

摘要

An image display device (10) has a display panel (60) and a liquid crystal lens (40) disposed closer to the front surface side than to the display panel (60). The display panel (60) has a black matrix (68) in which a plurality of pixels are formed, and a front surface-side polarization plate (66) positioned on the front surface side of the display panel (60). The liquid crystal lens (40) is provided with the following: a first substrate (41) and a second substrate (42) which oppose each other; a first electrode layer (44) formed on the first substrate (41); a second electrode layer (45) having a plurality of electrodes (45a-45e) formed in a striped shape on the second substrate (42); and a liquid crystal layer (43) in which a lens effect is generated due to changes in the orientation direction of liquid crystal particles (49) in accordance with voltage imparted between the electrode layers (44, 45). In the second electrode layer (45), a plurality of electrodes (45a-45e) extend in a direction that inclines with respect to black lines (68b) that extend in a prescribed direction in the black matrix (68). The initial orientation direction of the liquid crystal particles (49) is substantially parallel with respect to the transmission axis of the front surface-side polarization plate (66).
