发明名称 LIQUID CRYSTAL DISPLAY ELEMENT
摘要 <p>PROBLEM TO BE SOLVED: To provide a liquid crystal element which is hardly affected by the parasitic capacitance of a TFT and has a wide angle of visibility. SOLUTION: A pixel electrode 22 is formed on a TFT substrate 11, a lower layer electrode 31 and an additional capacitance electrode 38 are formed on a counter substrate 12, a color filter 33, etc., are formed thereon and upper layer electrodes 35a, 35b are formed on a color filter 33, etc. The upper electrode 35a is connected to the lower electrode 31. Liquid crystal 13 is enclosed between the TUFT substrate 11 and the counter substrate 12 to constitute the liquid crystal display element. The driving voltage applied between the lower layer electrode 31 and the pixel electrode 22 is applied to the liquid crystal 13 as it is in a region where the upper layer electrode 35a is arranged, and is lowered by a color filter 33 and applied to the liquid crystal 13 in a region where the upper layer 35b is arranged. Further, the additional capacitance is individually connected to the liquid crystal capacitance in both regions. Consequently, the lowering of voltage of the pixel electrode 22 due to the parasitic capacitance of the TFT 21 is reduced.</p>
