linear structures each comprising a first linear conductor linearly extended in a first direction and one of a light emitting layer and light emitting parts, which is formed on the first linear conductor, the linear structures being substantially arranged in parallel,

first insulating lines each being linearly extended along the first direction and being arranged between the adjacent linear structures, which electrically insulate the linear structures from one another,

transparent second linear conductors which are substantially arranged in parallel along the first direction, each of the second linear conductors being extended in a wavy form in a second direction orthogonal to the first direction so as to cross the linear structures and the first insulating lines, the transparent second linear conductors being electrically contacted on the one of the light emitting layer and the light emitting parts at the front side to form light emitting portions which are arranged in a matrix, and the transparent second linear conductors being contacted on the first insulating lines at the rear side so that the light emitting portions are configured to emit light rays from the front side through the transparent second linear conductors, and

second insulating lines each being extended in a wavy form along the second direction and being arranged between the adjacent transparent second linear conductors, which electrically insulate the linear conductors from one another, the second insulating lines being contacted on the linear structures at the rear side and being contacted on the first insulating lines at the front side, and the linear structures, the first insulating lines, the transparent second linear conductors and the second insulating lines being braided in a mesh.
