  The display means 10 is, for example, a dot TFT type rectangular TFT liquid crystal display panel, and in this case, a predetermined display area 11 is formed by a plurality of display pixels 60 as shown in FIG. The display area 11 displays various vehicle information such as the vehicle speed based on detection signals from various sensors mounted on the vehicle.

  In the case of this example, one display pixel 60 is constituted by three sub-pixels of R pixel 61, G pixel 62 and B pixel 63, and a large number (plural) of display pixels 60 are provided. Are provided in a matrix.

  The light transmitting member 20 is formed substantially in a flat plate shape by a light transmitting synthetic resin material, and is disposed between the display means 10 and the turning member 30. Further, in this case, the light transmitting member 20 is configured to cover only 11 display areas provided corresponding to the display pixels 60 in the display unit 10 as shown in FIGS. It does not cover other pixels 70 of the display means 10 located at a position different from 60.

  That is, the light transmitting member 20 here is not rectangular like the display means 10 in its outer shape, and the portions corresponding to the other pixels 70 (that is, the upper left portion and the upper right portion in FIG. It has an irregular shape that is cut (that is, chamfered).

  The light transmitting member 20 is bonded (joined) to the display means 10 (display area 11) by the light transmitting adhesive 21. As the translucent adhesive 21, for example, an ultraviolet curable optical adhesive (transparent resin) can be applied. Then, a viewer who visually recognizes the vehicle instrument D can see through (view) various vehicle information displayed on the display area 11 through the light transmitting member 20 and the light transmitting adhesive 21.

  The facing member 30 is formed of, for example, a black synthetic resin material, and is configured as a covering member (visor) that covers the display means 10 so as to define the visible area (that is, the display area 11) of the display means 10 It has the case main-body part 32 which has the circular opening part 31 for exposing the translucent member 20 places corresponding to the area | region 11). In this case, it is assumed that the case body 32 constitutes the main part of the facing member 30.

  And, in FIG. 1, when the vehicle instrument D is divided into two equal parts in the vertical direction in FIG. 1, the case main body part 32 mainly includes the horizontal wall 33 provided on the lower side of the vehicle instrument D; When D is divided up and down approximately equally into two, the inclined wall portion 34 provided mainly on the upper side of the vehicle instrument D and the peripheral wall portions 35 located on the upper end side and the lower end side of the vehicle instrument D in FIG. The peripheral wall portion 35 is further provided with a first upright wall portion 36 provided so as to be connected to the horizontal wall portion 33 at the lower end side of the vehicle instrument D in FIG. 1, and the vehicle in FIG. At the upper end side of the instrument D, a second upright wall portion 37 provided so as to be connected to the inclined wall portion 34 is provided.

  Further, as shown in FIG. 3, a pair for reflecting the colored light L emitted from the other pixel 70 of the display means 10 located at a position different from the display pixel 60 on the inclined wall portion 34 in the case body 32. A pair of (two) reflecting portions 38 are provided, and the second upright wall portion 37 of the housing body portion 32 is opposed to (facing) each of the reflecting portions 38 with a predetermined gap S therebetween. Is provided.

  Note that the facing area 39 is configured as a light emission design area described later that can emit light upon receiving the colored light L, and the inclination angle thereof becomes steeper (larger than the inclination angle of the inclined wall portion 34 ) Is set up.

  Furthermore, here, as in the case of the display pixel 60, one other pixel 70 is formed by three sub-pixels of the R pixel 71, the G pixel 72 and the B pixel 73 (see FIG. 4). A plurality of other pixels 70 not covered by 20 are locally provided in the upper left portion and the upper right portion of the vehicle instrument D in FIG. 1 and concealed by the inclined wall portion 34. That is, the other pixels 70 can not be viewed directly from the viewer side due to the presence of the inclined wall portion 34.

  In addition, the reflection unit 38 can apply a white light reflection layer having high light reflectance, which is provided, for example, on the back surface of the inclined wall 34 corresponding to the top right of another pixel 70. , And functions as a light reflecting surface that reflects colored light L (here, green light) emitted from another pixel 70.

  Here, among the R pixel 71, the G pixel 72, and the B pixel 73 constituting the plurality of other pixels 70, the G pixel 72 emits light, and green colored light L is obtained. In order to obtain the blue colored light L, the B pixel 73 of the R pixel 71, the G pixel 72, and the B pixel 73 may emit light, and to obtain the red colored light L, the R pixel described above 71, G pixel 72, and B pixel 73 may be used to emit light, and to obtain white colored light L, all the R pixel 71, G pixel 72, and B pixel 73 may be emitted. Good.

  Further, the reflecting portion 38 is not limited to the white reflecting layer, but may be a reflecting surface having a high light reflectance in a mirror state, or may be a rough surface such as emboss processing that diffusely reflects the colored light L.

  Then, the colored light L reflected by the reflecting portion 38 is guided to the opposing region 39 of the second upright wall portion 37 through the gap portion S. In other words, the colored light L emitted from the other pixel 70 is bent at a substantially right angle by the reflecting portion 38, and the second upright wall facing (facing) the reflecting portion 38. It will be led (reflected) to the 37 opposing areas 39.

  Furthermore, when the colored light L reflected to the facing area 39 hits the facing area 39, the light path of the light is bent substantially at a right angle so as to be directed to the viewer side. At this time, the colored light L bent substantially at right angles to the facing area 39 is an opening hole locally formed between the inclined wall portion 34 and the second standing wall portion 37 so as to be continuous with the gap portion S Through the openings H respectively.

  Thus, a viewer who visually recognizes the vehicle meter D visually recognizes, as visual information, a pair (two) light emission design areas 80 (see FIG. 1) locally provided in the upper left portion and the upper right portion of the vehicle meter D. can do. The light emission design area 80 is displayed as light emission in green when the colored light L strikes the opposite area 39. For example, it is used as an ambient display unit for light emission display whether the vehicle is eco-driven or not. Can. For example, in the case where the fuel consumption state of the vehicle is good (that is, the eco state), the viewer (driver) who visually recognizes the instrument D for a vehicle can emit It can be easily recognized that the driving state is the eco-driving state.

  The circuit board 40 is made of, for example, a hard wiring board on which a wiring pattern is formed, and various electronic components such as a control unit 41 made of a microcomputer for causing display operation of the display means 10 and resistors and capacitors are conducted to the wiring pattern. It is connected. The circuit board 40 is electrically connected to the display means 10 using a connection member (not shown) such as a flexible wiring board.

  The housing 50 is formed of, for example, a synthetic resin material, and accommodates the circuit board 40 and the like provided with the control unit 41 and the like for operating the display means 10, and the cover member using appropriate fixing means such as hook fixing It is fixed at 30.

  As described above, in the present embodiment, the facing member 30 has the case main body 32 having the opening 31 for exposing the 20 light transmitting members corresponding to the display area 11. Is a reflection portion 38 for reflecting the colored light L emitted from another pixel 70 of the display means 10 which is at a position different from the display pixel 60 and is not covered by the light transmitting member 20, and a predetermined gap A facing area 39 facing the reflecting section 38 through the section S is provided, and the colored light L reflected by the reflecting section 38 is guided to the facing area 39 through the gap section S.

  Therefore, when the colored light L bent substantially at right angles in the facing area 39 passes through the opening hole H, the viewer visually recognizes the light emission design area 80 in which the light emitting display is caused by the colored light L striking the facing area 39. The appearance of the vehicle instrument D becomes interesting and novel, and the existing look-back member 30 is used (that is, the shape of the turn-back member 30 is devised) to produce a novel look Can provide a display device capable of

  Further, in the present embodiment, the display pixels 60 of the display means 10 are covered with the light transmitting member 20, and the other pixels 70 of the display means 10 excluding the display pixels 60 are the light transmitting member 20. Although an example not covered is described, for example, as shown in FIG. 5 as a first modified example of the present embodiment, both of the display pixel 60 and the other pixel 70 are covered by the light transmitting member 20. It is good also as composition. That is, in this case, the display means 10 and the light transmitting member 20 completely overlap, and the light transmitting member 20 is adhered to the display means 10 by the light transmitting adhesive 21.

  Even in this case, the colored light L emitted from the other pixel 70 passes through the light-transmissive adhesive 21 and the light-transmissive member 20 and travels to the reflection portion 38, and then the reflection portion The colored light L reflected by the light 38 sequentially reaches the gap S, the facing area 39, and the opening hole H in the same manner as in the above embodiment, so that the viewer can view the light emission design area 80. Similar effects can be obtained.

  In the present embodiment, an example in which the light emission design area 80 is provided in two places in the upper left portion and the upper right portion of the vehicle instrument D in FIG. 1 has been described. For example, as shown in FIG. 6 and FIG. 7 as a second modification of the present embodiment, the light emission design area 80 is provided in only one place in the upper central area (or lower central area) of the vehicle instrument D in FIG. Alternatively, three or more light emission design areas 80 may be provided.

  In the case where only one light emission design area 80 is provided at the upper center of the vehicle instrument D in FIG. 1 as shown in FIGS. 6 and 7, the shape of the opening 31 is not circular but rectangular. Is desirable. Further, as an example in which three or more light emission design areas 80 are provided, for example, a configuration in which four light emission design areas 80 are provided in the upper left portion, upper right portion, lower left portion and lower right portion of vehicle instrument D in FIG. Be

  Further, in the present embodiment, when the fuel consumption state of the vehicle is good, the green colored light L emitted from the other pixel 70 strikes the pair of facing areas 39, as shown in FIG. In the upper left portion and the upper right portion of D, an example in which a pair of light emission design areas 80 are displayed in green is described, but, for example, a pedestrian is going to pass from the right to the left in front of the vehicle (own vehicle) In such a case, the light emission design area 80 located in the upper right portion of the vehicle instrument D in FIG. 1 may be configured to emit light in yellow (or orange) instead of green.

  In this case, an obstacle detection means (not shown) for detecting a target obstacle in front of the vehicle (in front of the host vehicle) including a pedestrian etc. is provided, and the control unit 41 detects the obstacle detected by the obstacle detection means When information (for example, information indicating that the pedestrian is going to pass from the right to the left as described above) is received, other information located in the upper right portion of the vehicle instrument D in FIG. The display means 10 is operated so that yellow (or orange) colored light L is emitted from the 70 pixels of the light source, and the light emission design area 80 located in the upper right portion of the vehicle instrument D in FIG. The light is displayed.

  With such a configuration, a viewer (driver) who visually recognizes the instrument for vehicle D has some obstacle in the vicinity of the own vehicle (vehicle) due to the change of the luminescent color of the light emission design area 80 It becomes possible to easily grasp things, and it becomes possible to improve the alertness. In addition, when the pedestrian is going to pass the front of the vehicle from the right to the left, the light emission design area 80 on the right (upper right portion) of the vehicle instrument D in FIG. Since the light emission is displayed in orange), there is an advantage that the direction in which the obstacle exists can be intuitively grasped.

  In this case, as in the second modification, the light emission design area 80 may be provided at only one place in the upper central area (or lower central area) of the vehicle instrument D in FIG. When the pedestrian is going to pass the front of the vehicle from the right to the left, the control unit 41 first causes the other pixels 70 to display the light emission design area 80 displayed in yellow (or orange) only at the right end. After that, the other pixels 70 may be operated so that the light emission design area 80 displayed on the right end side flows from the right end side to the left end side of the light emission design area 80 with the passage of time. Since the light emission design area 80 is dynamically displayed following the movement of the pedestrian, the display device having a visual effect can be provided.

  Further, in the present embodiment, when the fuel consumption state of the vehicle is good, the green colored light L emitted from the other pixel 70 strikes the pair of facing regions 39, whereby the pair of light emission design regions 80 Although the example in which the light emission display is performed in green has been described, for example, when the fuel consumption state of the vehicle is not good (that is, in the non-eco state) as a third modification of this embodiment, under control by the control unit 41, Alternatively, the blue colored light L may be emitted from the other pixel 70 so that the pair of light emission design areas 80 may be made to emit light in blue.

  That is, this means that the control unit 41 receives an eco state signal (first state signal) indicating that the vehicle state is the eco state (first state), and the control by the control unit 41 is performed. And the green light (predetermined color) is emitted from the other pixel 70, the control unit 41 sets the second state different from the first state (i.e., the second state). When the non-eco status signal (second status signal) indicating that the non-eco status is received, another color (for example, blue) different from green (predetermined color) is displayed based on the non-eco status signal. By causing the display means 10 to perform display operation so that other colored light (not shown) having other color light (not shown) is emitted from the other pixels 70, it means that the pair of light emission design areas 80 are displayed in blue.

  That is, when the other colored light of blue emitted from the other pixel 70 strikes the pair of facing areas 39, the pair of light emission design areas 80 are light-emitting displayed in blue, and the viewer sees the driving state of the vehicle It can be easily recognized that it is not in the eco-driving state.

  In the third modification described above, the light emission color of each light emission design area 80 is changed (variable) based on the quality of the fuel consumption state of the vehicle, but in the fuel consumption state of the vehicle, for example Alternatively, the light emission color of each light emission design area 80 may be changed according to the driving mode of the vehicle.

  Specifically, for example, the control unit 41 receives a normal mode signal (first state signal) indicating that the state of the vehicle (driving mode) is the normal mode (first state), and the control by the control unit 41 For example, under a situation where colored light L having a white color (a predetermined color) is emitted from another pixel 70, for example, the control unit 41 sets the vehicle state (driving mode) to the normal mode (first state) When a sport mode signal (second state signal) indicating that the second state (for example, sport mode) different from) is received, other colors different from white (predetermined color) are received based on the sport mode signal To cause the display means 10 to perform a display operation so that other colored light (not shown) having a color of (for example, red) is emitted from the other pixels 70, whereby each light emission design area 80 is displayed in red. To That.

  In this case, the viewer (driver) can appropriately select the normal mode or the sport mode by operating the driving mode conversion switch (not shown).

  As described above, according to the third modified example of the present embodiment, since the light emission color of the light emission design area 80 changes according to the condition of the fuel consumption of the vehicle, the viewer who visually recognizes the vehicle instrument D ( The driver) has the advantage of being able to easily recognize whether or not the driving state of the vehicle is in the eco-driving state by the change of the light emission color of the light emission design area 80. Similarly, since the light emission color of the light emission design area 80 changes according to the driving mode, the viewer (driver) judges whether the driving state of the vehicle is the normal mode or the sport mode. There is an advantage that it can be easily recognized by the change of the luminescent color of 80.
