Abstract

PURPOSE:To obtain a transmission type liquid crystal matrix display device having an invisible juncture of liquid crystal panels by disposing a lens or prism in said juncture. CONSTITUTION:A spacer 13 for connection is inserted between the transmission type display panels 11, 11' and the panels are connected by a connecting terminal 12. The prism 14 is installed at the center in the juncture of the panels 11, 11' in the state of permitting dispersion of light when viewed from an observation point 15. The spacer 13 cannot be observed when the transmission type liquid crystal matrix display device is driven. The part where the image in the juncture of the display panels is not displayed is thus thoroughly eliminated and the large-sized wall hanging television is realized.
