Display device with display panel forming image display and LCD panel having strip-shaped electrodes and light shielding portion
View Patent ↗There is provided a technology capable of reducing crosstalk at the time of 3D display in a display device using a liquid crystal lens that forms cylindrical lenses by controlling a voltage applied to a liquid crystal panel. The display device includes a liquid crystal display panel which includes a substrate including a plurality of strip-shaped transparent electrodes and a plurality of strip-shaped light shielding portions overlapping with the electrodes. The display device displays an image by switching a two-dimensional display and a three-dimensional display, and the cylindrical lenses making up a parallax barrier, are formed by controlling a refraction index of a liquid crystal layer.
1. A display device displaying an image by switching a two-dimensional display and a three-dimensional display, the display device comprising:
a display panel performing an image display; and
a liquid crystal display panel being disposed at a display surface side of the display panel; the liquid crystal display panel comprising:
a first transparent substrate comprising a planar transparent electrode;
a second transparent substrate being opposite to the first substrate; the second transparent substrate comprising:
a plurality of strip-shaped electrodes being formed of a transparent electrode material, extending in a first direction, and being arranged in parallel in a second direction intersecting with the first direction; and
a plurality of strip-shaped light shielding portions overlapping with the plurality of strip-shaped electrodes and extending in the first direction; and
a liquid crystal layer being interposed between the first substrate and the second substrate;
wherein a longitudinal direction in an initial orientation of liquid crystal molecules making up the liquid crystal layer intersects with the first direction and intersects obliquely with the second substrate;
wherein a width of the strip-shaped electrodes in the second direction is larger than a width of the strip-shaped light shielding portions;
wherein the light shielding portions are formed at a peripheral edge of the strip-shaped electrodes at the side where an end of liquid crystal molecules in the longitudinal direction is closer to the second substrate in the second direction; and
wherein cylindrical lenses extending in the first direction, being arranged in parallel in the second direction, and making up a parallax barrier, are formed by controlling a refraction index of the liquid crystal layer.
2. The display device according to claim 1 ,
wherein the display panel includes a liquid crystal display panel and a backlight device.
