Patent ID: 7106284

Claim:
A liquid crystal display device including a liquid crystal panel with a display region part composed of a plurality of source lines, a plurality of gate lines, and pixel cells arranged in a matrix at intersections between the source lines and the gate lines, the device comprising: a signal conversion part for converting an input image signal at a horizontal rate, generating a non-display signal during a slack time created by the conversion, and inserting the non-display signal in a display signal, which is the converted input image signal; a drive pulse generation part for generating various control pulses from an inputted synchronous signal; a source driver for receiving various signals from the signal conversion part and the drive pulse generation part, converting the display signal and the non-display signal to predetermined voltage values, and outputting them as a display signal voltage and a non-display signal voltage, respectively; a gate driver for receiving a control signal from the drive pulse generation part and supplying a drive voltage to the gate lines; a multiplexer part for supplying to a plurality of the source lines the display signal voltage and the non-display signal voltage from the source driver while switching the source lines in a time-sharing manner, the multiplexer part being disposed between the source driver and the display region part; and an intersection part where, when the source lines in the display region part are divided into groups of four, lines that correspond to two source lines located the second and third from an end in each group intersect each other, the intersection part being present between the source driver and the display region part.
