The invention provides a display apparatus which employs a display panel to display an image and has a large screen with a light weight and a sufficient structural strength and besides allows easy replacement of a light source of a lighting apparatus. The display apparatus includes a display panel, a circuit board, a light source unit and an optical panel all mounted on a rectangular frame formed from a combination of extruded members such as polygonal steel tubes. The frame serves also as an armor for the lighting apparatus, and this decreases the weight of the display apparatus. A light source of the light source unit can be replaced by taking out only the light source unit from the display apparatus. |

DETAILED DESCRIPTION It is an object of the present invention to provide a display apparatus which has a large screen with a light weight and a sufficient structural strength and allows easy replacement of a light source of a lighting apparatus.
In order to attain the object described above, according to an aspect of the present invention, there is provided a display apparatus including a display panel for displaying an image thereon, including a rectangular frame formed from a combination of bar members corresponding to four sides of the display panel, and a circuit board for driving the display panel mounted on the frame together with the display panel.
With the display apparatus, since the frame serves also as a chassis and besides has a rectangular shape composed of a combination of bar members corresponding to the four sides of the rectangle, a sufficient strength is assured.
The display apparatus may be constructed such that each of the bar members which form the frame is a polygonal tube-like member, and the polygonal tube-like member of at least one of the bar members has a groove for holding a part or a unit of the display apparatus.
Further, the display apparatus may be constructed such that the bar member is formed from a molded member, and the groove is formed in the molding direction.
The frame may support a light source unit of the display panel and serves also as a casing for the light source unit.
The light source unit may include a plurality of linear light sources mounted on a reflecting plate and is removably mounted on the frame.
The display apparatus may be constructed such that an opening is formed in the bar member of one of the four sides of the frame and a guide groove is formed on each of a pair of the bar members on the opposite sides of the one side with the opening, and a part or a unit of the display apparatus is inserted into the frame through the opening and held by the guide grooves.
According to another aspect of the present invention, there is provided a display apparatus, comprising a rectangular frame, a display panel attached to the front face side of the frame, and a light source unit including a light source, a reflecting plate and an optical panel, the light source unit being accommodated in and held by the frame
