Abstract

PURPOSE:To eliminate the adverse influence of the parasitic capacity of the thin film transistors provided at the points of intersection between gate lines and data lines and to obtain a liquid crystal display device having high reliablity, by maintaining said parasitic capacity at a specified ratio or below to the sum of the capacity values of a capacitor for charge holding and a liquid crystal. CONSTITUTION:A gate line 416, a data line 419, a common electrode 417, a liquid crystal driving electrode 420, thin film transistors (TRs) 412-414, contact holes 421-422, and a capacitor 423 for charge holding shown by obliquelines are formed on a liquid crystal display device of a matrix type. The parasitic capacity of the TRs 412-414 is maintained at a prescribed ratio or below to the sum of the capacitor for charge holding and the liquid crystal in order to prohibit lighting of the liquid crystal when the data signal is zero. The liquid crystal display device having reliability is thus obtd.
