Abstract: A gate driving circuit includes a stage configured to output a scan gate signal based on a scan clock signal, a voltage of a first node, and a voltage of a second node, and to output a sensing gate signal based on, a sensing clock signal, the voltage of the first node, and the voltage of the second node. The stage includes: a first sensing circuit configured to select a gate line to be sensed based on a S1 signal or to determine a frame reset based on a S7 signal; a first inverting circuit configured to control the first sensing circuit base on the S7 signal; and a second sensing circuit configured to control the voltage of the first node using the first sensing circuit based on a S2 signal. The frame reset is determined based on a maximum frequency of a variable frame frequency.

Abstract: A display device includes a via-insulating layer defining a trench including a substantially inclined surface and a substantially flat surface, a light emitting layer on the via-insulating layer and including a first portion parallel to the substantially inclined surface and a second portion disposed parallel to the substantially flat surface, and a color conversion layer on the light emitting layer. A first angle formed between a first imaginary straight line, which connects a point where the first portion and the second portion meet and an edge of the color conversion layer and forms an obtuse angle with the first portion, and a second imaginary straight line, which extends perpendicular to the first portion, is greater than a second angle formed between a travel direction of a light having a greatest luminous intensity among lights emitted from the first portion and the second imaginary straight line.

Abstract: A display device includes: an array of pixels disposed on a display area; a connection pad disposed on a pad area; a transmission line electrically coupled with the connection pad; and a conductive dummy pattern disposed under the transmission line. A part of the conductive dummy pattern overlaps the transmission line in a plan view. The transmission line transmits a driving signal or a power signal to the array of pixels. The connection pad includes a pad conductive layer electrically coupled with the transmission line, and a passivation layer disposed on the pad conductive layer. The passivation layer covers at least a side surface of the pad conductive layer and defines an opening overlapping the conductive dummy pattern and the transmission line in the plan view.
