Liquid-crystal display panel

Abstract

Abstract PURPOSE:To eliminate such trouble that the effective display screen of the display panel becomes smaller, inhibiting an air bubble confined in a seal part from moving, and easily manufacture the large-sized panel by employing double seal constitution in which multi layered constitution of an internal and an external seal layer formed on the peripheral surface of the panel is formed. CONSTITUTION:Internal seal layers 11 and 12 arranged at a panel internal surface side in parallel to the external seal layer 10 formed on the panel peripheral surface are coupled mutually at the opening part 15 of the external seal layer 10, but the seal layers 11 and 12 have a gap 16 of proper width communicating with the panel inside which is not linked with the parallel external seal layer. The gap 16 of the internal seal layers serves as an intake for an air bubble produced in the gap. If there is an air bubble in a fine gap between liquid crystal injected from the substrate opening part 5 and the substrate, the air bubble moves following the flow of the injected liquid crystal to move through the gap 20 between the internal and external seal layers. Further, the air bubble passes through the gap between internal and external seal layers 10 and 11, or 10 and 12 as the charging of liquid crystal advances and then stops at the coupling part 15 of the internal and external layers (the innermost position 21 of seal layer gap).
