<p><P>PROBLEM TO BE SOLVED: To provide an active matrix liquid crystal display device of a lateral electric field type that suppresses short-circuiting between video signal wiring lines and source electrodes and can achieve high yield. <P>SOLUTION: The source electrode 606 has a first portion connected to a thin film transistor and a second portion connected to a pixel electrode 609, with the second portion positioned around a central part between video signal wiring lines 604. The positional relation between the source electrode 606 and the video signal wiring line 604 is defined by the sum of values obtained by dividing a width of each portion of the source electrode 606 opposing to at least a part of the video signal wiring lines 604 by the distance between that portion and the video signal wiring line 604. In an intersection of the pixel electrode 609 and the common signal wiring line 602, an angle made by the edge of the pixel electrode 609 and the edge of the common signal wiring line 602 is controlled to an acute angle different from that in a display region so as to generate a strong fringe electric field as a forward rotation electric field and to prevent reverse rotation of liquid crystal molecules. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
