Abstract:
A liquid crystal display device, comprising:a first substrate; a second substrate; a liquid crystal layer interposed between the first substrate and the second substrate; a sealing member formed of a sealing material for confining the liquid crystal layer between the first substrate and the second substrate, the sealing member defining a sealing portion; wherein the first substrate includes: a plurality of gate signal lines, a plurality of source signal lines, a plurality of switching devices disposed in the vicinity of intersections of the plurality of gate signal lines and the plurality of source signals lines, a plurality of pixel electrodes respectively connected to the plurality of source signal lines through the plurality of switching devices, and an interlayer insulating layer provided below the plurality of pixel electrodes and covering the plurality of switching devices, the plurality of gate signal lines and the plurality of source signal lines; wherein the second substrate includes a counter electrode opposing the plurality of pixel electrodes with the liquid crystal layer interposed therebetween; and wherein the first substrate includes a plurality of terminals of different heights covered by the interlayer insulating layer at the sealing portion, the terminals being randomly spaced from one another on the first substrate, wherein a maximum height difference Y of adjacent terminals at the sealing portion is about 0.5 &mgr;m or less; and wherein a maximum height of protruding portions of the interlayer insulating layer along a top surface thereof is about 0.5 &mgr;m or less proximate the sealing portion due to said maximum height difference Y of adjacent terminals at the sealing portion.
