Abstract

Provided is a display apparatus capable of reducing the scale of a drive circuit and decreasing the frame. A display area in which pixels are provided in matrix, a scanning line drive circuit for driving scanning lines, and a signal line drive circuit for driving signal lines are provided on a support substrate. The pixel within the display area is constituted with a plurality of dots. Each dot corresponds to a color filter of a certain color. The dot is in a laterally long shape, i.e. in a shape extending in a direction along the scanning lines. In other words, each dot is in a shape extending in parallel with the longitudinal direction of the signal line drive circuit. The color filters are of lateral stripe type, for example.

Claims (19)

1. A display apparatus, comprising:

a display part where pixels, each being constituted with a single or a plurality of dots, are arranged in matrix on a support substrate in a first direction and a second direction;

a first circuit provided on outer side of the first direction of the display part on the support substrate; and

a second circuit whose scale is larger than that of the first circuit, which is provided on outer side of the second direction of the display part on the support substrate, wherein:

the dot is in a shape that is longer in the first direction than the second direction,

the display part has a non-rectangular external shape,

the second circuit is constituted with a plurality of circuit elements, each having a circuit part, a wiring part, and a space part in the first direction, which are arranged in the first direction at a constant repeated pitch; and

a following relation is satisfied where, in one of the circuit elements, a proportion of the wiring part and the space part occupying the repeated pitch is c, a ratio of length in the first direction of the circuit part to length of the second direction is b, and number of the plurality of colors is k,

b+c> 1 /k.

2. A display apparatus, comprising:

a display part where pixels, each being constituted with a single or a plurality of dots, are arranged in matrix on a support substrate in a first direction and a second direction;

a first circuit provided on outer side of the first direction of the display part on the support substrate; and

a second circuit whose scale is larger than that of the first circuit, which is provided on outer side of the second direction of the display part on the support substrate, wherein:

the dot is in a shape that is longer in the first direction than the second direction,

the display part has a non-rectangular external shape,

at least one of the plurality of dots comprises a light-emitting element,

the second circuit is constituted with a plurality of circuit elements, each having a circuit part, a wiring part, and a space part in the first direction, which are arranged in the first direction at a constant repeated pitch; and

when at least one of the plurality of dots comprises the light-emitting element, a following relation is satisfied where, in one of the circuit elements, a proportion of the wiring part and the space part occupying the repeated pitch is c, a ratio of length in the first direction of the circuit part to length of the second direction is b, and number of the plurality of luminance colors is k,

b+c> 1 /k.
