Abstract

An aperture LAR of a light-emitting portion is changed in diameter (size) from the center portion of a screen to the peripheral portion thereof. In this manner, any displacement observed between the aperture LAR and a vapor deposition region VAR of an organic EL material is controlled. The aperture LAR is preferably larger in size at the center portion of the screen, and smaller in the peripheral portion thereof. As such, a light-emitting layer is vapor-deposited on a substrate correctly for every pixel so that a high-quality self-emitting display including organic EL display can de derived.

Claims

1. A self-emitting display in which a display region is plurally arranged in a matrix, wherein

a non-display region at a center portion of a screen is wider in width than a non-display region at a peripheral portion of the screen, or

the display region at the center portion of the screen is narrower than the non-display region at the peripheral portion of the screen.

7. The self-emitting device according to claim 1, wherein

a pixel line is formed with n of the pixels arranged along the second direction, and a light-emitting region provided to both the 1st and nth pixels is narrower in width along the second direction than a light-emitting region provided to the mth (where m is an integer, satisfying 1<

m<

n) pixel.

2. A self-emitting display, comprising:

an insulation film with an aperture portion plurally arranged in a matrix; and

a light-emitting material placed in the aperture, wherein a non-display region at a peripheral portion of a screen is wider in width than the aperture at a center portion of the screen, or

the non-display region at the peripheral portion of the screen is narrower in width than the aperture at the center portion of the screen.

3. A self-emitting display in which a display region is plurally arranged in a matrix, wherein

a non-display region is increased in width from a center portion of a screen toward a peripheral portion of the screen, or

a display region is decreased in width from the center portion of the screen toward the peripheral portion of the screen.

4. A self-emitting display, comprising:

an insulation film with aperture portions arranged in a matrix; and

a light-emitting material placed in the aperture, wherein

a non-display region between the apertures is increased in width from a center portion of a screen toward a peripheral portion of the screen, or

a display region at a center portion of a screen is decreased in width from the center portion of the screen toward a peripheral portion of the screen.

5. A self-emitting display including a display screen with a plurality of pixels those are two-dimensionally arranged along a first direction and a second direction that is orthogonal to the first direction, wherein

N (where N is an integer of 3 or more) of the pixels forms a pixel row along the first direction, and in the pixel row, a light-emitting region provided to both the 1st and Nth pixels is narrower in width along the first direction than a light-emitting region provided to the Mth (where M is an integer, satisfying 1<

M<

N) pixel.

6. The self-emitting display according to claim 9, wherein po1 the integer M is a value equal to ½

of the integer N, or a value derived by rounding up ½

of the integer N.

8. A self-emitting display in which an organic EL device including a pair of electrodes and a light-emitting layer therebetween is plurally arranged in a matrix, and one of the electrodes connected with a current supply line via a thin film transister, wherein

the current supply line is extending to a side of the matrix, and is narrowed in width toward a center portion of the screen.
