Definitions
- the present invention relates to a liquid crystal display device. More specifically, the present invention relates to a liquid crystal display device that can display an image three-dimensionally.
- Patent Document 1 discloses a liquid crystal display device using a parallax barrier in which intervals between light-transmitting regions are uniform in order to obtain a wide viewing angle.
- liquid crystal panel rectangular pixel areas are arranged in a matrix, and for each pixel area, an image for the right eye and an image for the left eye are alternately displayed for each column, for example. It is configured as follows.
- the parallax barrier and the liquid crystal panel described above are such that when the observer looks at the display device, only the image information for the left eye reaches the left eye and only the image information for the right eye reaches the right eye.
- a parallax barrier is disposed on the display surface side of the liquid crystal panel.
- TFT elements and spacers for keeping the cell thickness constant may be disposed in the pixel region.
- the area where the TFT elements, spacers, and the like are arranged is a light-shielding part, so that image display cannot be performed, and it becomes a non-display part.
- the shape of the display part in the pixel area has a concave portion in part instead of the rectangular shape described above. It becomes a complicated shape.
- the pixel area having a display area with a complicated shape as described above can appropriately cover a necessary portion in a parallax barrier having a light-shielding area and a light-transmitting area having a uniform width.
- the image information for the right eye and the image information for the left eye may not be sufficiently separated. Therefore, depending on the position of the viewpoint, a part of pixels that cannot be shielded from light may be seen, and a phenomenon called crosstalk may occur in which right-eye and left-eye images appear to be mixed.
- the present invention has been made in view of the above situation, and even when a liquid crystal panel including a pixel region having a display portion with a complicated shape is used, crosstalk does not occur and stereoscopic image display is favorably performed.
- An object of the present invention is to provide a liquid crystal display device that can be used.
- the inventors of the present invention have made various studies on a liquid crystal display device that can display a three-dimensional image display satisfactorily. Even when a liquid crystal panel including a pixel region having a display portion with a complicated shape is used, the shape of the light-shielding region of the parallax barrier is a rectangular shape, and these are arranged in parallel. Image information for the left eye and image information for the left eye cannot be sufficiently separated, and crosstalk occurs, and the shape of the light-shielding area of the parallax barrier depends on the shape of the display area of the pixel area. It has been found that the change can suppress the occurrence of crosstalk while ensuring the necessary transmissivity, and the inventors have arrived at the present invention by conceiving that the above problems can be solved brilliantly.
- the present invention is a liquid crystal display device including a liquid crystal panel having a plurality of pixel regions and a parallax barrier that covers the panel surface of the liquid crystal panel.
- Each pixel region includes a display unit and a non-display unit.
- the display unit has a recess at least in part, and the parallax barrier has a light-transmitting region and a light-blocking region arranged at equal intervals, and the light-blocking region of the parallax barrier is formed on the liquid crystal panel.
- the liquid crystal display device has a convex part aligned with the concave part, and the width of the translucent region is narrow in the region where the convex part is formed.
- the liquid crystal panel is not particularly limited, but an active matrix liquid crystal panel is preferable because crosstalk hardly occurs between adjacent pixels.
- An active matrix liquid crystal panel includes a thin film transistor array substrate (hereinafter also referred to as a “TFT (Thin Film Transistor) array substrate”), and includes a pixel region having a display region with a complicated shape as described above. Therefore, the present invention can be preferably applied.
- TFT Thin Film Transistor
- an active matrix liquid crystal panel has a configuration in which a liquid crystal layer is held via an alignment film between a TFT array substrate and a counter substrate arranged at a predetermined interval. Then, by controlling the electric field strength applied between the pixel electrode of each pixel region formed on the TFT array substrate side and the common electrode formed on the counter substrate side, the alignment state of the liquid crystal in each pixel region is controlled. By changing the light transmittance, the image is displayed.
- Each pixel region has a display portion having a recess at least in part and a non-display portion formed in the recess.
- This concave portion is provided in order to arrange a TFT element, a spacer, and the like, and it is preferable that the area is as small as possible in consideration of the light transmittance of the pixel region.
- the parallax barrier partially blocks light transmitted through the liquid crystal panel, and has a configuration in which a band-shaped light transmitting region and a light shielding region are arranged at equal intervals.
- the light-shielding region is formed along the arrangement direction of the pixel region for the right eye and the pixel region for the left eye, is in a light-shielding state when a voltage is applied (on state), and is not applied with a voltage (off state) ) In a light-transmitting state, and can be switched as needed.
- equally spaced means that the arrangement interval between the band-like light transmitting region and the light shielding region may be completely the same or substantially the same, but more specifically, 3D It is preferable that they are the same to the extent that display can be realized.
- the liquid crystal display device is a display device that can easily switch between 2D display and 3D display.
- the switching between the on state and the off state described above can be easily realized by configuring the parallax barrier with a liquid crystal panel, and by using such a parallax barrier, switching between 2D display and 3D display can be easily performed. .
- the light-shielding region of the parallax barrier has a convex portion aligned with the concave portion formed in each pixel region, and the width of the light-transmitting region is narrow in the region where the convex portion is formed.
- the width of the light-shielding region of the parallax barrier is increased in the pixel range where the width of the opening is partially narrow. Crosstalk can be reduced without reducing the light transmittance of the region.
- the configuration of the liquid crystal display device of the present invention is not particularly limited by other components as long as such components are essential.
- the convex portion and the concave portion have the same length in the direction orthogonal to the protruding direction of the convex portion. Thereby, the said effect can be heightened.
- the arrangement interval of the convex portion and the arrangement interval of the concave portion are equal, without reducing the transmissivity of the pixel region as described above. Crosstalk can be reduced.
- equal means that the arrangement interval is the same as long as each effect of the present invention is exhibited, and may be completely the same or substantially the same.
- the pixel region includes a first column in which a plurality of pixel regions for the right eye are arranged, and a second column in which a plurality of pixel regions for the left eye are arranged.
- the light shielding regions are arranged along the column direction, and the liquid crystal panel and the parallax barrier are the first column and the first column when viewed from the normal direction of the liquid crystal panel. Examples include those arranged such that the boundary with the second row overlaps with the center along the arrangement direction of the light shielding regions. In other words, the center along the arrangement direction of the light shielding region is the center in the longitudinal direction of the light shielding region. According to this configuration, the image for the right eye and the image for the left eye can be reliably separated.
- the normal direction of the liquid crystal panel means the normal direction of the main surface of the liquid crystal panel.
- the liquid crystal panel and the parallax barrier are convex portions formed in a light shielding portion that constitutes a pixel area of the liquid crystal panel and a light shielding area of the parallax barrier when viewed from the normal direction of the liquid crystal panel. If the portions are arranged so as to be aligned along the protruding direction of the convex portions, the image for the right eye and the image for the left eye can be more reliably separated to reduce crosstalk.
- the right-eye image and the left-eye image are obtained while ensuring the necessary light transmittance even when a liquid crystal panel including a pixel region having a display portion with a complicated shape is used. And a liquid crystal display device excellent in 3D display characteristics can be realized.
