  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a first embodiment of the invention will be described with reference to the accompanying drawings. The case where the invention is applied to a vehicle display device will be described as an example.

  The display device of this embodiment includes a circuit board 1, a light source 2, a housing 3, a liquid crystal unit (first display) 4, a pointer-type meter (second display) 5, and a front panel (see-through). Panel) 6.

  The circuit board 1 is a well-known hard circuit board on which a light source 2 for a display board is mounted. A housing 3 molded of white synthetic resin or the like is disposed on the circuit board 1, and the liquid crystal unit 4 is held by the housing 3.

  The liquid crystal unit 4 mainly includes a liquid crystal display panel 41, a case 42, a light guide plate 43, a liquid crystal light source 44, and a panel holder 45.

The liquid crystal display panel 41 is a dot matrix type having pixels (dots) arranged in a matrix. Although details are omitted (not shown), the first glass substrate 41a and the second glass substrate 41b on which the transparent electrode made of ITO and the routing electrode connected to the transparent electrode are formed are overlapped to seal the periphery. After fixing with an agent, liquid crystal molecules are sealed between the glass substrates 41a and 41b, and a smoke-like polarizing film is pasted on the glass substrates 41a and 41b, for example.

  Although not shown, the case 42 has substantially the same shape as the liquid crystal display panel 41 and is made of metal or synthetic resin.

  Although not shown, the light guide plate 43 is made of a synthetic resin such as colorless and transparent acrylic or polycarbonate, and a light receiving portion is provided on a side surface facing the liquid crystal light source 44. In addition, fine irregularities (textures) are formed on the back surface so that light from the light source for liquid crystal 44 incident on the light guide plate 43 from the light receiving part is reflected by the irregularities and directed toward the surface side of the light guide plate. It has become. The light guide plate 42 is accommodated in the case 42.

  As shown in FIG. 2, the panel retainer 45 is made of, for example, a stainless steel plate that is a metal material, and has a panel edge 46 that restrains the peripheral portion of the liquid crystal display panel 41. At this time, the panel edge portion 46 constitutes a boundary portion B between the display unit 4 and the pointer type instrument 5 together with an opening portion to be described later of the display plate 51.

  The liquid crystal unit 4 configured in this manner has various vehicle information such as vehicle speed, outside temperature, travel distance, route guidance information, inter-vehicle distance information, in-vehicle audio, and the like on the center side of the display area when the light source for liquid crystal 44 is turned on. An information image (not shown) composed of information is displayed, and a hollow rectangular display image G along the inner edge of the panel edge 46 is displayed in a display area adjacent to the boundary B with the pointer-type instrument 5.

  The pointer-type meter 5 constitutes, for example, a fuel meter and an engine tachometer with the display plate 51 and the pointer 52 and is disposed on the left and right of the liquid crystal unit 4.

  The display board 51 has an opening 53 that accommodates the liquid crystal unit 4 and an index portion (not shown) that is an instruction target of the pointer 52. In this case, the opening 53 covers a part of the boundary portion B. Constitute.

As shown in FIG. 2, the front panel 6 is a transparent synthetic resin, and a lens portion 61 is formed at a location corresponding to the boundary area B and the display area of the display image G.

The lens unit 61 is a convex lens protruding toward the liquid crystal display panel 41 side, and has a semi-cylindrical shape. When the light that forms the display image G is transmitted, the lens unit 61 refracts the light so that the display image G expands, and thereby the display image G is displayed on the boundary B and the display area of the display image G. A refraction image KG is formed, and the refraction image KG makes the boundary portion B (panel edge portion 46) invisible.

Here, the hatched portion in FIG. 1 is a region where the display image B is displayed, and the outside thereof is a boundary B region. The display region of the display image G and the boundary B region are combined. This area becomes the display area of the refracted image KG. As a result, the refraction image KG is visually recognized as an image that covers the display area and the boundary B area of the display image B. That is, the display image G magnified by the lens unit 61 is magnified outward (in the direction of the arrow in FIG. 2) beyond the hatched portion (the region in which the display image G is displayed), whereby the boundary portion B and the display image are displayed. G is covered by the refraction image KG.

As described above, in the present embodiment, in a display device including at least two displays adjacent to each other and the transparent panel 6 that continuously covers the display surface side of these displays, at least one of the two displays is provided. The display panel G includes a display that displays a display image G in a display area adjacent to the boundary B of each display. The fluoroscopic panel 6 refracts the light when the light forming the display image G is transmitted to Since the boundary portion B is hidden by the refracted image KG by having the lens portion 61 that forms the refracted image KG of the display image G, the display continuity and uniformity are improved even when a plurality of displays are arranged adjacently, Visibility can be improved.

Further, in the present embodiment, since the lens unit 61 includes a magnifying lens that magnifies the display image G, the display image G can be made an enlarged image, so that the refraction image KG itself can be displayed as a seamless continuous image. , Can improve the appearance. That is, by forming the lens unit 61 so as to include the display image G forming region and the corresponding region of the boundary B, the refraction image KG itself can be displayed as a seamless continuous image.

FIG. 3 shows a modified example of the lens unit 61 as the second embodiment. In this embodiment, the lens unit 61 is formed into a Fresnel lens shape. Similar to the embodiment, a refraction image KG obtained by enlarging the display image G can be displayed, and an equivalent effect can be expected.

FIG. 4 shows another modified example of the lens unit 61 as the third embodiment. In this embodiment, the lens unit 61 has a prism lens shape, and the display image G is shifted in the lateral (outward) direction. The image KG is displayed, and even with such a configuration, the boundary B can be made invisible by the refraction image KG. In this case, the display image G is also visually recognized together with the refraction image KG.

FIG. 5 shows another modified example of the lens unit 61 as the fourth embodiment. In this embodiment, the lens unit 61 is formed on the liquid crystal unit 4 side of the panel member 6 and on the opposite side thereof. .
