Abstract
A display device includes: a display panel including a substrate and a display driving component mounted on the substrate; a backlight unit; and a heat dissipation member present on that surface of the substrate which is opposite to the region in which a display driving component is mounted and on that side of the backlight unit which is opposite to the display panel, the heat dissipation member being made of a highly thermally conductive material and having slits for discharging gas inside the heat dissipation member to outside the heat dissipation member.
Claims5
A display device, comprising:
- a display panel including a substrate and a display driving component mounted on the substrate;
- a backlight unit including a light source and facing the substrate;
- and
- a heat dissipation member integrally including:
- a display panel coinciding portion on a surface of the substrate which surface is opposite to a region in which the display driving component is mounted;
- a light source coinciding portion present on a side of the backlight unit which side is opposite to the display panel;
- and
- a connecting portion connecting the display panel coinciding portion and the light source coinciding portion with each other,
- the heat dissipation member being made of a highly thermally conductive material and having slits for discharging gas inside the heat dissipation member to outside the heat dissipation member, the slits being present in the display panel coinciding portion, the connecting portion, and the light source coinciding portion, and the slits including at least one of a first slit and a second slit, the first slit straddling the display panel coinciding portion and the connecting portion, the second slit straddling the connecting portion and the light source coinciding portion.
A method for producing a display device including (i) a display panel including a substrate and a display driving component mounted on the substrate and (ii) a backlight unit including a light source and facing the substrate,
- the method comprising the steps of:
- placing a heat dissipation member in such a manner that the heat dissipation member covers part of a front surface of the backlight unit and at least part of a back surface of the backlight unit, the heat dissipation member integrally including:
- a display panel coinciding portion;
- a light source coinciding portion;
- and
- a connecting portion connecting the display panel coinciding portion and the light source coinciding portion with each other;
- and
- placing the substrate on the heat dissipation member on a side of the front surface of the backlight unit,
- the heat dissipation member being made of a highly thermally conductive material and having slits for discharging gas inside the heat dissipation member to outside the heat dissipation member, the slits being present in the display panel coinciding portion, the connecting portion, and the light source coinciding portion, and the slits including at least one of a first slit and a second slit, the first slit straddling the display panel coinciding portion and the connecting portion, the second slit straddling the connecting portion and the light source coinciding portion.
