摘要：
A display device having an improved configuration of contact area, which increases the production yield and reduces a product cost. A contact area (50) is disposed in such a manner as to contain a part, or the whole, of a pixel electrode edge portion as an area which is the area between a signal line (22) and a signal line (23) and extends along a scanning line (20), and connection between a pixel electrode (10) and a source electrode (40) is made in this area. A rectangular contact hole (52) is formed, but it may be replaced with a group of contact holes. A capacitance ratio RAcl is set so as to satisfy the relation RAcl=Cx/COMAX > VLCMAX/(VCLMIN - VCLMAX) where Cx is a parasitic capacitance, COMAX is a maximum value of a pixel capacitance, VCLMIN is a voltage at which a transmission factor becomes minimal and VCLMAX is a voltage at which the transmission factor becomes maximal. According to this construction, pixel defect at the time of inferior contact can be apparently eliminated.

具有改进的接触面积配置的显示装置，其提高了生产成本并降低了产品成本。 接触区域（50）以包含作为信号线（22）和信号线（23）之间的区域的区域的像素电极边缘部分的一部分或全部的方式设置，以及 沿着扫描线（20）延伸，并且在该区域中形成像素电极（10）和源电极（40）之间的连接。 形成矩形接触孔（52），但可以用一组接触孔代替。 电容比RAcl被设定为满足关系式RAcl = Cx / COMAX> VLCMAX /（VCLMIN-VCLMAX），其中Cx是寄生电容，COMAX是像素电容的最大值，VCLMIN是传输 因子变得最小，VCLMAX是传输因子变为最大的电压。 根据该结构，可以明显地消除接触不良时的像素缺陷。
