Abstract

There is provided an automobile display device including: a transmitting member that is made of a light-transmitting resin, that includes, at a rear face side thereof, an irradiated portion to which light from a light source is irradiated, and that includes, at a front face side thereof, a display portion emitting light by transmitting the light that has been irradiated to the irradiated portion, plural through holes being formed at portions of the transmitting member excluding the display portion during primary molding of two-color molding; and a non-transmitting member that is made of a non-light-transmitting resin, that is filled into the through holes and provided at the front face side and the rear face side of the transmitting member during secondary molding of the two-color molding, and that exposes the irradiated portion and the display portion.

First claim

What is claimed is:

1. An automobile display device comprising:
a transmitting member that is made of a light-transmitting resin, that includes, at a rear face side thereof, an irradiated portion to which light from a light source is irradiated, and that includes, at a front face side thereof, a display portion emitting light by transmitting the light that has been irradiated to the irradiated portion, a plurality of through holes being formed at portions of the transmitting member excluding the display portion during primary molding of two-color molding; and
a non-transmitting member that is made of a non-light-transmitting resin, that is partly filled into the through holes during secondary molding of the two-color molding, and that exposes the irradiated portion and the display portion,
wherein the non-transmitting member comprises an outer layer provided at the front face side of the transmitting member, an inner layer provided at the rear face side of the transmitting member, and a connecting portion that is filled into the through holes to connect between the outer layer and the inner layer, the outer layer and the inner layer being wider than the connecting portion.

2. The automobile display device according to claim 1 , wherein a thickness of the non-transmitting member provided at the front face side of the transmitting member is equal to or less than three times a width of a leading end portion of the display portion.

3. The automobile display device according to claim 1 , wherein a width of a base portion of the display portion is equal to or greater than 1.5 times a width of a leading end portion of the display portion.

4. The automobile display device according to claim 2 , wherein a width of a base portion of the display portion is equal to or greater than 1.5 times a width of a leading end portion of the display portion.

5. The automobile display device according to claim 1 , wherein
edges of the outer layer and the inner layer of the non-transmitting member in a width direction respectively extend beyond a width of the connecting portion, such that extended edges of the outer layer and the inner layer form an anchoring portion that holds the non-transmitting member to the transmitting member.

6. The automobile display device according to claim 1 , wherein
the outer layer of the non-transmitting member is disposed inside an indentation formed on the transmitting member such that a front face side of the outer layer of the non-transmitting member is co-planar with the display portion of the transmitting member.

7. The automobile display device according to claim 5 , wherein
the edge of the outer layer in a width direction forms a tapered shape wherein a front face side of the edge of the outer layer is wider than a rear face side of the edge of the outer layer.
