Abstract: An electro-optic apparatus includes a substrate; a first conductive member disposed on one side of the substrate; a pixel electrode; a second conductive member disposed outside of a display region; a dummy pixel electrode; and an insulating layer disposed between the pixel electrode and the dummy pixel electrode, and the substrate. The pixel electrode includes a first pixel electrode layer overlapping the first conductive member, and a second pixel electrode layer, overlapping an opening region of a pixel, thinner than the first pixel electrode layer. The dummy pixel electrode includes a first dummy pixel electrode layer overlapping the second conductive member, and a second dummy pixel electrode layer, overlapping the first dummy pixel electrode layer, thinner than the first dummy pixel electrode layer. The insulating layer and the first dummy pixel electrode layer in a portion not overlapping the second conductive member face each other with a gap therebetween.

Abstract: An object is to provide a semiconductor device having a structure in which parasitic capacitance between wirings can be efficiently reduced. In a bottom gate thin film transistor using an oxide semiconductor layer, an oxide insulating layer used as a channel protection layer is formed above and in contact with part of the oxide semiconductor layer overlapping with a gate electrode layer, and at the same time an oxide insulating layer covering a peripheral portion (including a side surface) of the stacked oxide semiconductor layer is formed. Further, a source electrode layer and a drain electrode layer are formed in a manner such that they do not overlap with the channel protection layer. Thus, a structure in which an insulating layer over the source electrode layer and the drain electrode layer is in contact with the oxide semiconductor layer is provided.
