Abstract

A display device having a display element is configured such that the extending directions of electrodes are made different from each other among upper, lower, left and right pixels.

Claims

1. A display device includes

an upper frame, an intermediate frame and a lower frame, wherein,

the upper frame has a projection portion projected to the lower frame side,

the lower frame has a projecting portion projected to the upper frame side,

the intermediate frame has a through hole,

the projecting portion of the upper frame and the projecting portion of the lower frame are connected at the position of the through hole.

2. A display device according to claim 1, the upper frame and the lower frame are directly contacted at the position of the through hole.

3. A display device according to claim 2, the upper frame and the lower frame are fixed by a screw.

4. A display device includes

an upper frame, an intermediate frame and a lower frame, wherein

the upper projecting portion has an upper projecting portion projected to the upper frame side,
