Embodiment approach 1
[0062] A liquid crystal display device has a liquid crystal display panel in which a liquid crystal layer is provided between a pair of substrates, and a voltage is applied to the liquid crystal layer using electrodes provided on the substrates to change the orientation of liquid crystal molecules to perform display. In this embodiment, drive control of pixels is performed on an active matrix substrate on which thin-film transistors (TFTs) and pixel electrodes are arranged in a matrix for each pixel. figure 1 It is a schematic plan view showing the circuit configuration of pixels on the active matrix substrate in the display device according to the first embodiment. figure 2 is along figure 1 Schematic cross-sectional view of the structure of the A-B line cross-section.
[0063] Such as figure 1 As shown, TFTs and pixel electrodes 18 are arranged for each pixel on the active matrix substrate. The TFT has the following structure: On one side of the portion where the TFT sem...
Embodiment approach 2
[0072] This embodiment relates to a mode in which storage capacitor wiring is provided in the boundary region between pixels in an odd row (Nth row) and pixels in an even row (N+1th row), and in the even row (N+th row) An additional circuit is provided between the pixels of the next odd-numbered row (row N+2). Image 6 It is a plan view schematically showing a circuit configuration of a pixel on an active matrix substrate in the display device according to Embodiment 2, using circuit symbols. Image 6 Medium, C S L(N, N+1) represents the storage capacitor wiring used to drive the pixels of the Nth row and the (N+1)th row, and GL(N) and GL(N+1) respectively represent the wiring used to drive the Nth row , the gate lines of the pixels in the (N+1)th row, SL(M), SL(M+1), SL(M+2) represent the gate lines used to drive the Mth column, the (M+1)th column, The source line of the pixels in the (M+2)th column.

Embodiment approach 3
[0086] This embodiment relates to a transflective liquid crystal display device. Figure 7 It is a schematic plan view showing the structure of a pixel in the display device of the third embodiment. Figure 8 is along Figure 7 Line C-D is a schematic cross-sectional view of a part of the structure of a cross-section of a liquid crystal display panel. In the active matrix substrate of the transflective liquid crystal display device of this embodiment, the pixel electrodes 18 are formed by transparent electrodes 52 that transmit light and reflective electrodes 53 that reflect light incident from the liquid crystal layer side. The reflective electrode 53 is arranged at one end of the region where the transparent electrode 52 is arranged, and the region where the reflective electrode 53 is arranged constitutes a reflective region. On the other hand, the remaining region in the pixel electrode 18 where the reflective electrode 53 is not formed constitutes a transmissive region. ...
