Abstract:
1. An in-plane switching type liquid crystal display device comprising: (a) a first substrate including (a1) a plurality of gate lines and a plurality of data lines formed thereon such that said gate lines are substantially perpendicular to said data lines, (a2) at least one pixel electrode and at least one common electrode alternately formed thereon in each of pixels defined by said gate and data lines, and (a3) an insulating film covering said pixel and common electrodes therewith; (b) a second substrate facing said first substrate, and including (b1) a black matrix layer having a pattern of opening, (b2) a color layer, and (b3) a planarizing film covering said black matrix layer and said color layer therewith and having a planarized surface; and (c) a liquid crystal layer sandwiched between said first and second substrates, wherein when a voltage is applied across said pixel electrode and said common electrode, liquid crystal existing on extensions of said data lines are caused to rotate in a plane substantially in parallel with said first substrate, and wherein said planarizing film is formed with a recess having a predetermined cross-section such that a gap between said first and second substrates varies due to said recess.
