Display device
First Claim
1. A display device comprising a front surface panel, a back surface panel and an outer frame, wherein the front surface panel, the back surface panel and the outer frame are fixedly secured to each other by an adhesive agent, and a sealed space formed in the inside of the display device which is surrounded by the front surface panel, the back surface panel and the outer frame is set at a pressure lower than the outside pressure, the improvement being characterized in that the outer frame is comprised of a plurality of wall members and portions of at least some neighboring wall members which are engaged with each other have oblique surfaces at least partially, a crossing angle made by a normal line of the oblique surfaces and a normal line of the front surface panel or the back surface panel is set to an acute angle, and both oblique surface portions which are engaged with each other are fixedly secured to each other by way of the adhesive agent.

Abstract
The present invention provides a display device which can maintain a gap between a front surface panel 1 and a back surface panel 2 at a given value and maintain the air-tightness of a sealed space defined between the front surface panel 1 and the back surface panel 2 even when the gap is relatively large. To achieve such an object, the display device includes the back surface panel 1, the front surface panel 2 and the outer frame 3, the outer frame 3 is constituted of a plurality of divided wall members 3X1, 3X2, 3Y1, 3Y2 and 3C1 to 3C4. Further, at least at some portions where neighboring wall members are engaged with each other, oblique surfaces 3P are formed and a crossing angle which is made by a normal line of the oblique surfaces 3P and a normal line of the back surface panel 1 or the front surface panel 2 is set to an acute angle.
