no. 1 Embodiment approach

[0042] figure 1 It is a diagram for explaining the display device 101 according to the first embodiment of the present invention, and is a perspective view showing the appearance of the vehicle-mounted panel unit 501 having the display device 101 . figure 2 is a configuration diagram for explaining the display device according to the first embodiment of the present invention, wherein figure 2 (a) is the front view of the display device in "audio operation mode", figure 2 (b) is a front view of the display device in the "air conditioner operation mode". exist figure 1 omitted in figure 2 Display pattern P01 and display pattern P02 are shown in .

[0043] The display device 101 according to the first embodiment of the present invention is used, for example, in figure 1 The vehicle panel unit 501 is shown. like figure 1 As shown, the vehicle-mounted panel unit 501 mainly includes an operation panel device 402 applied to the display device 101; a liquid crystal disp...

no. 2 Embodiment approach

[0072] Image 6 It is a cross-sectional structural view for explaining the display device 102 according to the second embodiment of the present invention. Figure 7 It is a diagram for explaining the display device according to the second embodiment of the present invention, and is a side configuration view showing an example of an optical path in the display device. Figure 7 Indicates that the lighting part SB2 is on. Figure 8 It is a diagram for explaining the display device 102 according to the second embodiment of the present invention, and is a side configuration view showing an example of an optical path in the display device 102 . Figure 8 Indicates that the illuminating part SB2 is off. For ease of illustration, Figure 7 and Figure 8 Part of the hatching is omitted. In addition, the display device 102 of the second embodiment is different from the first embodiment in the structure of the light emitting member SB2. The same symbols are assigned to the same st...

Deformed example 1

[0095] In the above-mentioned first embodiment, the black-based display panel PN1 is used, and in the above-mentioned second embodiment, the white-based display panel PN2 is used, but it is not limited to black and white, for example, red or blue may be used. Department of other colors. For example, in Figure 9 In the case of the red display panel CPN shown, the colorless and light-transmitting substrate CR9, the white and light-transmitting atomized layer CR3, the silver-colored and light-shielding color layer CR5, and the black and light-shielding layer can be combined. Combination of light-shielding black layer CR7. Furthermore, if Figure 9 As shown, it is more preferable to provide a white-type and light-transmitting white layer (white layer) CR4 between the mist layer CR3 and the colored layer CR5 because the chroma of red can be increased.

Abstract

The objective of the present invention is to provide a display device which uses a simple configuration to make a display pattern on an illuminated part invisible when the illuminated part is not being illuminated. This display device (101) is configured from a display panel (PN1) which has an illuminated part (AL1) and a non-illuminated part (NL1), and an illuminating member (SB1) which is disposed behind the display panel (PN1) and which illuminates the illuminated part (AL1), the display device (101) being characterized by: the display panel (PN1) having a translucent substrate (19) and a translucent smoke layer (13) formed on the rear surface (19b) of the substrate (19) on the illuminating member (SB1) side thereof; a light-blocking color layer (15) being formed on the main surface (13m) of the smoke layer (13) on the illuminating member (SB1) side thereof; and the color layer (15) having an opening (15k) for forming the illuminated part (AL1).

Description

technical field [0001] The present invention relates to a display device used in operation panels of various electronic devices, and more particularly to a display device in which a display pattern to be irradiated with light cannot be seen when light is not irradiated. Background technique [0002] Conventionally, the following input devices have been used in the operation panels of various electronic equipment, that is, by irradiating light to display patterns such as icons or marks on the display part (display panel), so that the user can use it even at night (in a dark place). Ability to see the operable area. At this time, in order to improve the appearance of the product to be applied, a display pattern that is invisible when not irradiated with light and visible only when irradiated with light is sought. [0003] As a prior art corresponding to the above-mentioned requirements, Patent Document 1 (Prior Art Example 1) discloses the following Figure 11 The operation p...
