Patent ID: 7719638

Claim:
A semi-transmissive liquid crystal display device, comprising: a first substrate which is partitioned by signal lines and scanning lines provided in a matrix pattern in which a pixel is formed on respective positions, said pixel comprising a reflective part and a transmissive part, a reflective pixel electrode being provided in said reflective part, and a transmissive pixel electrode being provided in said transmissive part, a second substrate which is formed with a color filter and a common electrode, and a liquid crystal layer which is provided in between said two substrates, the reflective pixel electrode which is provided on said reflective part and said transmissive part being formed so as to overlap with said scanning lines and said signal lines via an interlayer film when viewed from the upper side, wherein an entire width of the signal lines in said transmissive part is broader than a width of the signal lines corresponding to said reflective part, wherein an overlapping width of the transmissive pixel electrode and a signal line in said transmissive part is formed, wherein an overlapping width of the reflective pixel electrode and said signal line in said reflective part is formed, and wherein said overlapping width of the signal line and the transmissive pixel electrode is larger than said overlapping width of the signal line and the reflective pixel electrode.
