摘要： Large size flat display panels are used in many technical fields, with television (TV) sets, personal computers (PCs) and advertising equipment. A multiple panel display device has been developed which employs a plurality of separate flat-surface display panel modules united by adhesion together into a matrix array of rows and columns. Juncture sections of the panels have non-displayable regions between adjacent ones of the panels. To avoid seam lines visible to the human eye, the seams are minimized in width. To this end, the peripheral ends of display panels are provided with a concave/projection configuration or gap for limiting excessive expansion of a sealing material used. This significantly reduces the width of such non-display region at the juncture section of neighboring display panels bonded together.
