Abstract: A display device includes an active matrix substrate including a plurality of pixels and a driver unit. The driver unit includes a flexible substrate, a first wiring pattern disposed on the flexible substrate, a demultiplexer circuit or a multiplexer circuit supported by the flexible substrate and connected to the first wiring pattern, and a source driver IC supported by the flexible substrate and connected to the first wiring pattern. The driver unit is connected to a display panel, and a TFT of the plurality of pixels and a TFT of the demultiplexer circuit or the multiplexer circuit have semiconductors different from each other.

Abstract: Provided are a liquid crystal panel capable of sufficiently reducing noise without an increase in load on the system, and an active retarder for 3D image display and a display device each including the liquid crystal panel. The liquid crystal panel includes: pixels adjacent to one another; a pair of substrates; pixel electrodes corresponding to the respective pixels; common electrodes overlapping the respective pixel electrodes; a liquid crystal layer; and an input unit. The pixel electrodes, the common electrodes, and the liquid crystal layer are disposed between the pair of substrates. The common electrodes are adjacent to one another across an aperture in a plan view. The aperture overlaps a boundary between the pixel electrodes. The input unit is configured to input a same signal to the common electrodes.

Abstract: When a current-driven display device with an internal compensation method operates in a pause driving mode, a non-light emission period according to a light emission duty is provided in both a refresh frame period and a non-refresh frame period, and an on-bias applying period for applying on-bias to a drive transistor in a pixel circuit is provided in both the non-light emission periods. In the non-light emission period in the refresh frame period, an on-bias applying period is provided in a period from when data writing with threshold compensation is performed to when the light emission period starts. Thus, even when the light emission duty is low, the difference in the stress state of the drive transistor between the refresh frame period and the non-refresh frame period is reduced.

Abstract: A display device includes a first substrate, a second substrate, a first electrically conductive portion and a second electrically conductive portion disposed between the first substrate and the second substrates. The first substrate includes a first line, a second line, a first connection electrode projecting from the first line toward the second line, and a second connection electrode projecting from the second line toward the first line. The second substrate includes a first electrode, a third connection electrode electrically connected to the first electrode and disposed to overlap the first connection electrode, a second electrode, and a fourth connection electrode electrically connected to the second electrode and disposed to overlap the second connection electrode. The first electrically conductive portion overlaps and contacts the first connection electrode and the third connection electrode. The second electrically conductive portion overlaps and contacts the second connection electrode and the fourth connection electrode.
