<p>PURPOSE:To reduce the number of defective picture elements by collecting picture elements, which are divided into two and four by a scanning line and a signal line, into one picture element. CONSTITUTION:An equivalent circuit of one picture element part consists of two thin film transistors (TR) 3 and 3', and a liquid crystal is divided to liquid crystals 5 and 5' also. With respect to display picture elements in X-number of rows and Y-number of columns, the display panel of a character display device of X=Y=500 has 500,000 thin film TRs. If the rate of non-defective thin film TRs is 99.9%, half defective picture elements whose halves are not operated are 500, but completely defective picture elements which are not operated completely are reduced to a half.</p> |
