Embodiment approach 1

[0149] First, the display panel device 1 according to Embodiment 1 of the present invention will be described. figure 1 It is a plan view of the display panel device 1 according to Embodiment 1 of the present invention.

[0150] The display panel device 1 according to Embodiment 1 of the present invention includes a plurality of light emitting regions (not shown) formed in a row direction and a column direction perpendicular to the row direction (in a matrix). Multiple light emitting areas such as figure 1As shown, a light-emitting pixel portion (hereinafter, simply referred to as “pixel portion”) 12 is provided for each light-emitting region. Therefore, a plurality of pixel units 12 are arranged in a row direction and a column direction perpendicular to the row direction (in a matrix) for each light emitting region.

[0151] Each pixel unit 12 is connected to a pixel unit 12R that emits red light (hereinafter referred to as a “red pixel unit”), a pixel unit 12G that emits g...

Embodiment approach 2

[0202] Next, use Figure 8 A display panel device 2 according to Embodiment 2 of the present invention will be described. Figure 8 It is a partially enlarged cross-sectional view of the display panel device 2 according to Embodiment 2 of the present invention. In addition, in Figure 8 in, for with figure 2 The same configurations of the shown display panel device 1 according to Embodiment 1 of the present invention are assigned the same reference numerals, and description thereof will be omitted.

[0203] The display panel device 2 according to Embodiment 2 of the present invention is different from the display panel device 1 according to Embodiment 1 of the present invention in the structure of the resin layer and sealing resin.

[0204]In the display panel device 2 according to Embodiment 2 of the present invention, the resin layer 21B of the lens portion 20B has a convex portion 21 b protruding toward the organic EL portion 10 side. The convex portion 21b is formed t...

Embodiment approach 3

[0217] Next, use Figure 10 A display panel device 3 according to Embodiment 3 of the present invention will be described. Figure 10 It is a sectional view of the display panel device 3 according to Embodiment 3 of the present invention. In addition, in Figure 10 in, for with image 3 The same configurations of the shown display panel device 1 according to Embodiment 1 of the present invention are assigned the same reference numerals, and description thereof will be omitted.

[0218] In the display panel device 3 according to Embodiment 3 of the present invention, the resin layer 21C of the lens portion 20C has the second recessed portion 21c recessed toward the glass layer 23 side. The second concave portion 21c is formed between the concave portions 21a.

[0219] In the second concave portion 21c, the partition wall 24 is filled until the surface on the organic EL unit 10 side of the resin layer 21C becomes substantially flush with the surface. A light-absorbing mater...

Abstract

Provided is a display panel device wherein the difference in the light extraction efficiency for each color pixel unit and the variation in the service life between each color pixel unit are reduced. Specifically, disclosed is a display panel device having an organic EL unit (10) arranged with a red color pixel unit (12R), a green color pixel unit (12G), and a blue color pixel unit (12B), wherein the display panel device is provided with: a glass layer (23) which is disposed above the organic EL unit; a resin layer (21) which is disposed between the glass layer and the organic EL unit and which is formed, on the surface on the side of the organic EL unit, with a plurality of recesses (21a) that correspond to each pixel unit and that depress towards the glass layer; and lenses (22) which fill each of the plurality of recesses (21a) until the surface meets the surface of the resin layer on the side of the organic EL unit. Moreover, the refractive index of the blue-colored lens (22B) which fills the recess of the resin layer corresponding to the blue color pixel unit (12B) is at least higher than the refractive index of the red-colored lens (22R) which fills the recess of the resin layer corresponding to the red color pixel unit (12R).

Description

technical field [0001] The present invention relates to a display panel device and a manufacturing method thereof, and particularly to a display panel device having an organic light-emitting layer and a manufacturing method thereof. Background technique [0002] In recent years, as a self-luminous display panel device, a display panel device including an organic EL (Electro Luminescence, electroluminescence) element including an organic light-emitting layer has attracted attention. A display panel device including an organic EL element includes a red pixel portion including a red organic light emitting layer that emits red light, a green pixel portion including a green organic light emitting layer that emits green light, and a blue pixel portion that emits blue light. The blue pixel portion of the organic light-emitting layer. [0003] In a display panel device including an organic EL element, it is important to improve the extraction efficiency of light emitted from organi...
