Liquid crystal display device having nut member fixed on housing
View Patent ↗A liquid crystal display device includes a liquid crystal display element, a frame member having a frame-shaped part which is arranged at a displaying surface side of the liquid crystal display element and having a display window exposing a displaying surface of the liquid crystal display element, and a side wall which is extended from the frame-shaped part along a thickness direction of the liquid crystal display element. A light source is arranged opposite to another surface of the liquid crystal display element which is opposite to the displaying surface thereof and irradiates the another surface of the liquid crystal display element with illumination light. A housing member which houses the light source has a main surface opposite to a frame-shaped part of the frame member and a side wall formed at a periphery of the main surface thereof.
1. A liquid crystal display device comprising:
a liquid crystal display element;
a frame member having a frame-shaped part which is arranged at a displaying surface side of the liquid crystal display element and having a display window exposing a displaying surface of the liquid crystal display element, the frame member having a side wall which extends from the frame-shaped part along a thickness direction of the liquid crystal display element;
a light source which is arranged opposite to another surface of the liquid crystal display element opposite to the displaying surface thereof, the light source irradiating the another surface of the liquid crystal display element with illumination light; and
a housing member having a main surface opposite to the frame-shaped part of the frame member and a side wall formed at a periphery of the main surface thereof, the housing member housing the light source therein;
wherein the frame member is fixed to the housing member so as to cover the main surface of the housing member with the frame-shaped part of the frame member while an outer surface of the side wall of the housing member is covered with an inner surface of the side wall of the frame member;
wherein a nut member having a tapped hole is fixed to the housing member by a first screw which is screwed to the housing member, the tapped hole is positioned in the outer surface of the side wall of the housing member, and
wherein a second screw is screwed into the tapped hole in a direction transverse to the thickness direction of the liquid crystal display element and fixes the liquid crystal display device to an exterior case, the first screw being covered with the frame member.
2. A liquid crystal display device according to claim 1 , wherein the frame member has an opening formed at a part of the side wall thereof, and the second screw is screwed to the tapped hole of the nut member through the opening.
3. A liquid crystal display device according to claim 1 , wherein the housing member has an opening formed at a part of the side wall thereof which is opposite to the tapped hole of the nut member.
4. A liquid crystal display device according to claim 1 , wherein the frame member is made of metal and the housing member is molded of resin material.
5. A liquid crystal display device according to claim 1 , wherein the housing member has another tapped hole formed at a part of the side wall thereof, and the first screw is screwed to the another tapped hole.
