A liquid crystal display, and its manufacturing process, are provided in which antistatic measures are taken in the manufacturing process to prevent the occurrence of static failure before the formation during that process of the short ring. On a glass substrate 2, gate lines 46 are formed. The gate lines 46 are disconnected to form a discharge gap 50 with projections 52 and 54 on both sides of the gap 50. The discharge projections 52 and 54 are positioned substantially at the center of the edges of the disconnected portion of the gate lines 46. A gate insulation film 56 is formed on the gate lines 46 and in the discharge gap 50. Two through holes 58 are made in the gate insulation film 56 in the vicinity of the discharge projections 52 and 54 of each gate line 46. A metal wiring layer 48 is formed on the gate insulation film 56 so as to fill in the through holes 58 where the discharge gap is no longer necessary.
