DISPLAY DEVICE HAVING INTEGRAL CAPACITORS AND REDUCED SIZE

摘要

The output stage of a monolithically integrated gate lines driver circuit of a display device has a capacitor boosted, source-follower configuration in which a relatively large area transistor (Tr1) receives drive power at its drain from a clock signal providing rail (CK), a source of the transistor drives a respective gate line and a relatively large area boost capacitor (C1) connects to gate and the source of the transistor. In order to reduce consumption of substrate area, the relatively large area boost capacitor is laid out to overlap the transistor while a relatively thick first insulating layer of relatively low dielectric constant positioned between the transistor and the overlying boost capacitor.

1. A display device, comprising:
a display panel including a display area in which a plurality of pixel units are positioned on a light-passing substrate and in which a nondisplaying peripheral area is also disposed on the substrate and adjacent to the display area; and a gate lines driver positioned on the substrate and in the peripheral area and including a transistor and a capacitor, wherein the capacitor is formed to overlap the transistor but to not be highly capacitively coupled to a drain portion of the transistor and where a capacitive coupling minimizing, first insulating layer is interposed between at least between the drain portion of the transistor and the overlying capacitor.
