Display device
View Patent ↗A display device includes a thin film transistor substrate including transistors each controlling the amount of light emission of each pixel and a counter substrate arranged to be placed over the thin film transistor substrate. The thin film transistor substrate includes an insulating substrate as a base material, a circuit layer including the transistors formed on the insulating substrate, an organic layer interposed between two electrodes, and an organic insulating layer arranged between the circuit layer and the organic layer and formed of an organic insulating material formed thicker in each pixel region than in an inter-pixel region.
1. A display device comprising:
a thin film transistor substrate comprising a plurality of pixels and transistors each controlling the amount of light emission of the pixel; and
a counter substrate arranged to be placed on the thin film transistor substrate, wherein
each of the plurality of pixels comprises a light-emitting region and a non-light-emitting region, and
the thin film transistor substrate comprises
an insulating substrate as a based material,
a circuit layer including the transistors formed on the insulating substrate,
an organic layer which is formed on the circuit layer and is interposed between two electrodes,
and
a first organic insulating layer between the circuit layer and the organic layer,
wherein
one of the two electrodes is a lower electrode formed under the organic layer while the other electrode is an upper electrode formed on the organic layer,
an edge of the lower electrode is covered with the first organic insulating layer,
the organic layer includes an emitting layer, a first portion connected to each of the two electrodes, and a second portion connected to the upper electrode and the first organic insulating layer, and
a first distance is shorter than a second distance, wherein the first distance is an average distance between the first portion and the counter substrate, and the second distance is an average distance between a part of the second portion and the counter substrate.
2. The display device according to claim 1 , wherein
the first portion of the organic layer is arranged between a color filter and the insulating substrate in the light-emitting region,
the second portion of the organic layer is arranged between a black matrix and the insulating substrate in the non-light-emitting region.
3. The display device according to claim 1 , wherein
the first organic insulating layer is isolated in each of the light-emitting regions.
4. A display device comprising:
a thin film transistor substrate comprising a plurality of pixels and transistors each controlling the amount of light emission of the pixel; and
a counter substrate arranged to be placed on the thin film transistor substrate, wherein
each of the plurality of pixels comprises a light-emitting region and a non-light-emitting region, and
the thin film transistor substrate comprises
an insulating substrate as a based material,
