Embodiment ）

[0044] Embodiments are not limited to the above-described embodiments. Examples of other embodiments will be described.

[0045] In the foregoing embodiments, the buffer sheet 70 is made of, for example, white polyurethane. However, the color and material of the buffer sheet 70 may be appropriately changed. For example, a black polyurethane sheet that absorbs most of the direct light DL may be inserted as a buffer element between the LCD unit 20 and the light guide 40 . A typical cushioning material such as a sheet member of rubber or the like may also be inserted as a cushioning member between the LCD unit 20 and the light guide 40 .

[0046] In the foregoing embodiments, the shape of the light blocking portion 75 is a trapezoidal shape. However, the shape of the light blocking portion may be appropriately changed. As long as the light blocking portion 75 can cover the reaching area 42, the shape of the light blocking portion may be, for example, a rectangular shape, a se...

Abstract

A display device is disclosed, which includes a display unit, an opening element, a light source, a light transmitting element, and a buffer having a buffer main body portion and a light blocking portion. The buffer body part is supported between the display unit and the light transmissive member. The light blocking portion protrudes from the buffer body portion along an opposing surface of the light transmitting member opposite to the display unit, and covers an arrival area of ​​the opposing surface where direct light from the light source toward the opening of the opening member reaches.

Description

technical field [0001] The present disclosure relates to a display device for displaying information on a display screen. Background technique [0002] Patent Documents 1 and 2 disclose display devices including a liquid crystal display (LCD) unit and a light source for radiating light for illuminating a display screen of the LCD unit. As described in Patent Document 1, the LCD unit of this display device is held in a housing or the like such that the LCD unit is held between a cylindrical portion of a decorative member and a protruding portion opposed to the cylindrical portion. The display device of Patent Document 2 further includes a light guide located on the opposite side of the scale plate with reference to the LCD unit. The light guide has a base and an illuminating portion. The base portion extends from the irradiating portion toward a light source located other than a region overlapping with an opening of the scale plate in a display direction. Due to this struc...
