Problems solved by technology

However, if the oblique light emitted by the organic EL element of one of the adjacent sub-pixels is seen from an oblique direction through the sub-pixels, there is a possibility of color mixing between the adjacent sub-pixels.
In this way, there is a problem that the angle of view at which color display with red, green, and blue sub-pixels as display units can be seen within the originally desired color gamut becomes narrower.

[0142] Next, refer to Figure 11 Electronic equipment according to the second embodiment will be described. Figure 11 It is a schematic diagram showing the configuration of a head-mounted display as an electronic device according to a second embodiment.

[0143] like Figure 11 As shown, a head-mounted display (HMD) 1000 according to the second embodiment includes two display units 1001 provided corresponding to left and right eyes. The observer M wears the head-mounted display 1000 on his head like glasses, and can view characters, images, and the like displayed on the display unit 1001 . For example, if images in consideration of parallax are displayed on the left and right display units 1001 , stereoscopic video can be viewed.

[0144] The organic EL device 100 according to the first embodiment is mounted on the display unit 1001 . Therefore, it is possible to provide a compact and lightweight head-mounted display 1000 having high color purity and excellent ...

Abstract

The invention provides an electro-optical device and an electronic apparatus which can obtain high quality display in large visual angle. The electro-optical device includes a substrate; a first organic EL element that is formed in a first sub pixel on the substrate; a second organic EL element that is formed in a second sub pixel adjacent to the first sub pixel on the substrate; a sealing part that is formed to cover the first organic EL element and the second organic EL element; a first coloring layer that is formed in the first sub pixel on the sealing part; a second coloring layer that is formed in the second sub pixel on the sealing part; and a convex portion that has light transmission properties and is formed between the first sub pixel and the second sub pixel on the sealing part, in which the first coloring layer and the second coloring layer are disposed to overlap each other at an upper surface portion of the convex portion.

Description

technical field [0001] The present invention relates to an electro-optical device and electronic equipment including an organic electroluminescence (EL) element. Background technique [0002] Organic EL elements, which are light emitting elements, can be smaller and thinner than LEDs (Light Emitting Diodes: Light Emitting Diodes). Apps get a lot of attention. A combination of an organic EL element capable of emitting white light and a color filter has been proposed as means for realizing color display in such a microdisplay (for example, refer to Patent Document 1). [0003] In the electro-optical device (organic EL device) described in Patent Document 1, a sealing portion is formed to cover a plurality of organic EL elements arranged on a substrate, and a red (R) element is formed on the sealing portion by photolithography. , Green (G), blue (B) colored layers of the color filter. Each colored layer constituting the color filter is distinguished by a light-transmitting c...
