And a pair of substrates are bonded together with a sealant in a state where a gap corresponding to the thickness of the liquid crystal layer is maintained. For example, when the screen size of the liquid crystal display device 10 is 60 inches, the rectangular liquid crystal panel 20 has a short side dimension of about 750 mm and a long side dimension of about 1300 mm.

  Of the pair of substrates, one substrate is a CF (Color Filter) substrate, and the other substrate is a TFT (Thin Film Transistor) substrate. The TFT substrate is provided with a large number of TFTs and pixel electrodes, which are switching elements, arranged side by side on the inner surface facing the liquid crystal layer, and around these TFTs and pixel electrodes, gate wirings and source wirings forming a lattice shape are provided. It is arranged so as to surround it. The pixel electrode is made of a transparent electrode such as ITO (Indium Tin Oxide) or ZnO (Zinc Oxide).

  On the other hand, on the inner surface side facing the liquid crystal layer, a large number of color filters are arranged side by side on the CF substrate at positions corresponding to the respective pixels. The color filter is arranged so that subpixels of three colors of R (red), G (green), and B (blue) are alternately arranged. A light shielding layer (black matrix) for preventing color mixture is formed between the color filters. A counter electrode facing the pixel electrode on the TFT substrate side is provided on the surface of the color filter and the light shielding layer. In addition, an alignment film for aligning liquid crystal molecules contained in the liquid crystal layer is formed on the inner surface side of each substrate, and a polarizing plate is pasted on the outer surface side opposite to the inner surface side of each substrate. It is attached.

  The liquid crystal panel 20 applies a voltage corresponding to given image information to the pixel electrode of the CF substrate and the counter electrode of the TFT substrate, and applies an electric field to the liquid crystal layer, thereby changing the polarization state of the light passing through the liquid crystal layer. By changing, the amount of light transmitted through the polarizing plate provided on the CF substrate can be controlled.

  The backlight chassis 22a is made of metal and is formed in a substantially box shape opened to one side by a bottom plate formed in a horizontally long rectangular shape similar to the liquid crystal panel 20 and a side plate rising from the peripheral edge of the bottom plate. Yes.

  The light source 22b is installed on the inner surface of the bottom plate in the backlight chassis 22a and emits light to illuminate the liquid crystal panel 20. In the present embodiment, the light source 22b is configured as a direct-type LED backlight by arranging a plurality of LED (Light Emitting Diode) lamps in a matrix on the inner surface of the bottom plate, and individually controls each LED lamp. Thus, the light amount can be controlled for each area. The light source 22b is not limited to such a configuration, and may be configured as, for example, an edge light type LED backlight, or may be configured by arranging cold cathode tubes in parallel.

  The reflection sheet is made of a synthetic resin exhibiting white having excellent light reflectivity, and is laid so as to cover the inner surface of the bottom plate and the inner surface of the frame 24 attached to the side plate in the backlight chassis 22a. By this reflection sheet, most of the light emitted from the light source 22b can be guided to the opening side of the backlight chassis 22a.

Hereinafter, on the display surface 20a of the liquid crystal panel 20, a rectangular region that is not covered by the bezel 21 and is exposed to the outside is referred to as a “display region”. That is, the bezel 21 is a member that surrounds the display area V1. In this display area V1, a divided image corresponding to given image information is displayed.

  Therefore, when the multi-display device 1 is viewed from the front (that is, the side facing the display surface 20a), the bezel of each liquid crystal display device 10 is placed in a region sandwiched between the display regions V1 arranged in a plane. The surface of 21 is exposed and an image cannot be displayed. Thus, when the multi-display device 1 is viewed from the front, an area where an image cannot be displayed is referred to as a “non-display area”.

A frame-like region (hereinafter referred to as “second non-display region”) is also included.

  FIG. 3 is an enlarged perspective view showing the vicinity of a pair of bezels 21 arranged between a pair of adjacent display areas V1 in the multi-display device 1 according to the present embodiment. FIG. 3 shows a simplified structure of a pair of adjacent liquid crystal display devices 10. FIG. 4 is a schematic diagram for explaining the relationship between the reflective surface 30 formed on each pair of adjacent bezels 21 and the display surface 20 a of each liquid crystal display device 10 in the pair of adjacent liquid crystal display devices 10. is there.

  The bezel 21 of the liquid crystal display device 10 constituting the multi-display device 1 according to the present embodiment faces the display region V1 of the liquid crystal display device 10 and is a region near the bezel 21 in the display region V1 in the image display state. A reflection surface 30 for reflecting the outgoing light A1 emitted from V11 (hereinafter referred to as “edge region”) is formed.

  That is, when the multi-display device 1 is configured by arranging the liquid crystal display devices 10, in each pair of adjacent liquid crystal display devices 10, each liquid crystal display is included in the first non-display region V <b> 2 sandwiched between the pair of adjacent display regions V <b> 1. The bezel 21 of the device 10 is arranged, and the bezel 21 of one liquid crystal display device 10 faces the display region V1 of the one liquid crystal display device 10 and reflects the emitted light A1 from the edge region V11 of the display region V1. The bezel 21 of the other liquid crystal display device 10 faces the display region V1 of the other liquid crystal display device 10 and reflects the emitted light A1 from the edge region V11 of the display region V1. The reflecting surface 30 is provided.

  In the present embodiment, as shown in FIG. 4, the reflecting surface 30 formed on the bezel 21 has the other display region V1 that forms a pair of the emitted light A1 from the edge region V11 in the display region V1 and the display region V1. It is formed by an inclined surface that reflects toward the side, specifically, is a flat surface extending along the bezel 21, and an inclination angle θ [degree] formed with respect to the display surface 20a is 30 ≦ θ ≦. 45 is satisfied.

The bezel 21 is formed so that the reflecting surface 30 is dark gray. Specifically, such a reflecting surface 30 may be formed by vapor-depositing a dark gray paint, or may be formed by molding the bezel 21 with a dark gray synthetic resin. Here, dark gray is an achromatic color within a predetermined range, for example, CIE 1976 (L ^* a ^* b ^* ) color system display according to Japanese Industrial Standard (JIS Z8729), and L ^* value is 30-50.

  As the inclination angle θ of each reflection surface 30 is increased, the amount of the outgoing light A1 incident on the reflection surface 30 can be increased. However, if the inclination angle θ is increased too much, that is, between the pair of adjacent reflection surfaces 30. If the formed angle φ [degree] becomes an acute angle, the amount of reflected light A2 that wraps around decreases, and the effect of the wrapping of light, which will be described later, is reduced. Therefore, the reflecting surface 30 is preferably formed so that the inclination angle θ satisfies 30 ≦ θ ≦ 40 (in other words, 100 ≦ φ ≦ 120). Moreover, it is preferable that the bezel 21 is a narrow frame formed in the width dimension to about 6 mm.

  In this way, by causing each reflected light A2 to wrap around, the amount of light can be made dense in the space S above the pair of adjacent bezels 21, and the reflected light A2 reflected by each reflecting surface 30 interferes with each other. Can be made. Then, by increasing the amount of light in the space S above the pair of bezels 21, a state is realized as if a linear light source extending along the bezel 21 is provided above the pair of bezels 21. can do. By realizing such a state, it is possible to prevent the pair of bezels 21 from being recognized by an observer who views the display screen of the multi-display device 1 from the front side.

The amount of light is sparse. Therefore, in the multi-display device 100 according to the related art, the pair of bezels 121 are prevented from being recognized by an observer who visually recognizes the display screen of the multi-display device 100 from the front side as in the present embodiment. I can't.

  In the multi-display device 100 according to the related art, as shown in FIG. 8, a portion where the divided image is interrupted by the presence of the first non-display area V <b> 2 by an observer who views the display screen of the multi-display device 100 from the front side. In addition, a grid-like line L was visually recognized. On the other hand, in the multi-display device 1 according to the present embodiment, the amount of light can be increased in the space S above the pair of adjacent bezels 21, so that the first non-display area V <b> 2 is displayed as shown in FIG. 7. The grid line L based on it can be made inconspicuous. Thereby, it can prevent that the quality of the image displayed on the multi-display apparatus 1 whole falls.

  As described above, according to the present embodiment, the first non-display area in which the bezel 21 is arranged with a simple configuration in which the reflective surface 30 having the predetermined inclination angle θ is formed on the bezel 21 and at a low manufacturing cost. V2 can be made inconspicuous, and the quality of the image displayed on the entire multi-display device 1 can be prevented from being deteriorated.
