Abstract

An electronic panel, includes: a base substrate including a front surface, a rear surface opposite the front surface, and a plurality of side surfaces connecting the front surface and the rear surface to each other; a pixel definition layer on the front surface of the base substrate and having a plurality of openings defined therein; a plurality of emitting elements in the openings; and a spacer on the pixel definition layer and spaced apart from the openings, wherein a thickness of the spacer is equal to or greater than a thickness of the pixel definition layer.

Claims (23)

1. An electronic panel, comprising:

a base substrate including a front surface, a rear surface opposite to the front surface, and a plurality of side surfaces connecting the front surface and the rear surface to each other;

a pixel definition layer on the front surface of the base substrate and having a plurality of openings defined therein;

a plurality of emitting elements in the openings;

a spacer on the pixel definition layer and spaced apart from the openings, wherein the spacer is configured to control a reflection angle of light incident on the spacer to be different from or less than 30°,

wherein a ratio of a thickness of the pixel definition layer to a sum of thicknesses of the pixel definition layer and the spacer is equal to or less than 0.3; and

a plurality of signal lines between the base substrate and the pixel definition layer, the signal lines being electrically connected to the emitting elements, wherein a first signal line of the signal lines between adjacent openings is within a footprint of the spacer in a plan view and a second signal line of the signal lines between the adjacent openings is outside the footprint of the spacer in the plan view with the first signal line and the second signal line are disposed on a same layer,

wherein the spacer includes a first sidewall extending along a direction inclined at a first angle relative to an extending direction of a first side surface among the side surfaces, when viewed from the front surface, wherein the first angle is in a range of 45°±15° or 135°±15°, and

the spacer further includes a second sidewall extending in a direction perpendicular to the extending direction of the first side surface, when viewed from the front surface.

2. The electronic panel of claim 1 , wherein the pixel definition layer and the spacer have a unitary shape.

3. The electronic panel of claim 1 , wherein each of the openings includes:

a first side extending along a direction inclined at a first angle relative to an extending direction of the first side surface among the side surfaces, when viewed from the front surface; and

a second side connected to the first side and extending along a direction inclined at a second angle relative to the extending direction of the first side surface,

wherein one or more of the first angle and the second angle are in a range of 45°+15° or 135°+15°.

4. The electronic panel of claim 1 , wherein the spacer includes:

a third sidewall connected to the first sidewall and extending along a direction inclined at a second angle relative to the extending direction of the first side surface,

wherein one or more of the first angle and the second angle are in the range of 45°±15° or 135°±15°.

5. The electronic panel of claim 4 , wherein the spacer further includes the second sidewall extending in a direction perpendicular to the extending direction of the first side surface and having connection either with the first sidewall or with the third sidewall, when viewed from the front surface.

6. The electronic panel of claim 1 , wherein, when viewed from the front surface, an angle between an extending direction of the first side surface among the side surfaces and an extending direction of each of the signal lines is in a rage of 45°+15° or 135°+15°.

7. The electronic panel of claim 6 , wherein, when viewed in plan, the signal lines overlap the pixel definition layer.

8. The electronic panel of claim 1 , further comprising a plurality of mesh lines that lie on the pixel definition layer and have a plurality of mesh openings defined therein, the mesh openings corresponding to the openings of the pixel definition layer,

wherein the mesh lines include: a first mesh line extending along a direction; and a second mesh line extending along a intersecting direction intersecting the direction,

wherein, when viewed from the front surface, an angle between an extending direction of the first side surface among the side surfaces and each of the direction and the intersecting direction Is in a rage of 45°+15° or 135°+15°.
