According to an aspect, a stretchable device includes: a resin base member; and a strain gauge, a signal line, and an output line stacked on the resin base member. The resin base member includes: a plurality of bodies disposed separately from each other; and a plurality of hinges that couple the bodies adjacently disposed while meandering in an intersecting direction intersecting an imaginary line that couples the bodies adjacently disposed. The hinges include a first hinge and a second hinge that couple the bodies adjacently disposed. A meander length of the second hinge in the intersecting direction is longer than a meander length of the first hinge in the intersecting direction. The strain gauge is provided to the first hinge. The signal line and the output line are provided to the second hinge.

Stretchable electronic device

In a liquid crystal display device, a common electrode is formed on an organic passivation film, an interlayer insulating film is formed on the common electrode, a pixel electrode with a slit is formed on the interlayer insulating film, and a through hole is formed in the organic passivation film and the interlayer insulating film, so that the pixel electrode is connected to a source electrode of a TFT through the through hole. Further, the taper angle around the upper base of the through hole is smaller than the taper angle around the lower base. Thus, the alignment film material can easily flow into the through hole when the diameter of the through hole is reduced to connect the pixel and source electrodes, preventing display defects such as uneven brightness due to the absence of the alignment film or due to the alignment film irregularity around the through hole.

The first display panel includes a first substrate with a first terminal area in which a first terminal part is formed, and a second substrate which is opposed to the first substrate and has a thickness different from that of the first substrate. The second display panel includes a third substrate with a second terminal area in which a second terminal part is formed, and a fourth substrate which is opposed to the third substrate and has a thickness different from that of the third substrate. The first terminal area and the second terminal area do not overlap with each other in a plan view.

According to one embodiment, a display device includes a first display panel, a second display panel and an adhesive layer which adheres the first and second display panels. The first display panel includes a first scanning line, a first signal line, a first pixel electrically connected to the first scanning line and the first signal line, and the first pixel includes a first pixel electrode including first line portions extending parallel to the first signal line. The second display panel includes a second scanning line, a second signal line, and a second pixel electrically connected to the second scanning line and the second signal line, and the second pixel includes a second pixel electrode including second line portions intersecting the second signal line in plan view.

In a liquid crystal display device, a common electrode is formed on an organic passivation film, an interlayer insulating film is formed on the common electrode, a pixel electrode with a slit is formed on the interlayer insulating film, and a through hole is formed in the organic passivation film and the interlayer insulating film, so that the pixel electrode is connected to a source electrode of a TFT through the through hole. Further, the taper angle around the upper base of the through hole is smaller than the taper angle around the lower base. Thus, the alignment film material can easily flow into the through hole when the dimeter of the through hole is reduced to connect the pixel and source electrodes, preventing display defects such as uneven brightness due to the absence of the alignment film or due to the alignment film irregularity around the through hole.
