Title:
液晶表示装置及びその製造方法
Document Type and Number:
Japanese Patent JP4443476
Kind Code:
B2
Abstract:
Disclosed is a black matrix for a liquid crystal display device (LCD) having an impedance about equal to or more than 105Ω, a specific resistance about equal to or more than 1011 Ωcm, and a relative dielectric constant about equal to or less than 20 at a driving frequency of about 1 kHz to 100 kHz. The black matrix as disclosed has dielectric properties that minimize parasitic capacitance between the black matrix and the circuitry of the LCD, thereby preventing a signal delay in charging pixel electrodes that degrades the LCD image.
