Display apparatus

A display apparatus having a front and a rear, the display apparatus including (i) a display region to display information towards a display direction that is along a direction from the rear to the front and (ii) a light luminous region disposed in an area adjacently along an outer perimeter of the display region, the light luminous region being luminous by outputting light, both the display region and the light luminous region being arranged to be viewed by a viewer facing the front,

• the display apparatus comprising:
• a light source to emit light that is to be outputted from the light luminous region;
• a light guide member guiding and diffusing the light from the light source,
• a transmissive member made from light transmissive material, the transmissive member including
• a light input face aligned with the light guide member to receive the light via the light guide member,
• a light output face that has a belt-like extended shape having two extended end portions in an extended direction, the extended direction being defined as being along the outer perimeter of the display region and orthogonal to the display direction, the light output face forming the light luminous region by outputting the light inputted via the light input face, and
• an attenuation portion formed between the light input face and the light output face to attenuate the light transmitting from the light input face to the light output face;
• a first input-light shielding portion and a second input-light shielding portion each being formed between the light guide member and the transmissive member to prevent the light via the light guide member from entering the transmissive member;
• and
• an output-light shielding portion formed in a perimeter of the transmissive member to prevent the transmissive member from outputting light,
• wherein:
• the belt-like extended shape of the light output face has a width, the width being defined as being orthogonal to the extended direction and orthogonal to the display direction,
• the width decreasing in the extended direction from a midway point of the two extended end portions to each of the two extended end portions of the light output face;
• the attenuation portion has a thickness between the light input face and the light output face, the thickness being defined as being orthogonal to the extended direction and along the display direction,
• the thickness increasing in the extended direction from the midway point of the two extended end portions to each of the two extended end portions of the light output face;
• the transmissive member has an extended shape along the extended direction of the light output face, the extended shape having two end regions of a first end region and a second end region on the light input face,
• the transmissive member being inclined more to the rear with respect to the light output face as being extended from a midway point between the first end range and the second end range to each of the first end region and the second end region;
• the light guide member has an extended shape along the extended direction of the light output face, the extended shape having two end regions of a third end region opposing the first end region of the transmissive member and a fourth end region opposing the second end region of the transmissive member,
• the light guide member being inclined more to the rear with respect to the light output face as being extended from a midway point between the third end range and the fourth end range to each of the third end region and the fourth end region;
• the first input-light shielding portion is sandwiched between the first end region of the transmissive member and the third end region of the light guide member;
• and
• the second input-light shielding portion is sandwiched between the second end region of the transmissive member and the fourth end region of the light guide member,
• the transmissive member further including:
• a projection wall included in the attenuation portion, the projection wall projecting more towards the display direction than the output-light shielding portion formed in the perimeter of the transmissive member to prevent the transmissive member from outputting light,
• the projection wall having a summit face that inclines with respect to a virtual plane orthogonal to the display direction, the summit face serving as the light output face.
