Embodiment approach

[0074] In an exemplary embodiment of the method of manufacturing the display panel DP, the first insulating layer 10 may be formed using a plasma process, and the input region IR and the output region OR of the third part PP3 may be reduced. In such an embodiment, the first part PP1, the second part PP2, the line part SLP and the capacitive part CP may be reduced. In such an embodiment, the channel region CR of the third part PP3 is protected by the insulating pattern part IP1 such that the channel region CR of the third part PP3 is not reduced. According to an exemplary embodiment of the present invention, a portion of the semiconductor layer SCL may be reduced through a predetermined reduction treatment process.

[0075] The input region IR and the output region OR of the third part PP3 include metal reduced from the metal oxide semiconductor material of the semiconductor layer SCL. The first part PP1, the second part PP2, the line part SLP, and the capacitor part CP includ...

Abstract

A display panel includes: a base substrate including a pixel area and a peripheral area; a semiconductor layer provided on a part of the base substrate; a display element provided in the pixel area; and a first thin film transistor controlling the display element and including an input electrode, an output An electrode and a control electrode, wherein the semiconductor layer includes: a first part arranged on the input electrode of the first thin film transistor; a second part arranged on the output electrode of the first thin film transistor; and a third part connected to the first part and the second portion, overlap the control electrode of the first thin film transistor, and define a channel of the first thin film transistor.

Description

technical field [0001] The present disclosure relates to display panels. More particularly, the present disclosure relates to display panels with improved display quality. Background technique [0002] The display panel includes a plurality of pixels disposed on a base substrate. The base substrate may include a plurality of pixel regions and a peripheral region disposed adjacent to the pixel regions. Pixels may be respectively arranged in the pixel regions. [0003] Each pixel may include a display element and a circuit portion to control the display element. Display elements and circuit parts included in a pixel are provided in corresponding ones of the plurality of pixel areas. The aperture ratio of each pixel region is determined according to the ratio of the area of ​​the display element to the area of ​​the corresponding pixel region when viewed in a plan view. As the circuit part becomes complicated, the area occupied by the circuit part increases, so that the ap...
