Also, for example, the composition of the first light absorption layer 91 may be Ti _x O _y C _z , 0.5 < x < 4.5, 1.5 < y < 7.5, and 0.5 < z < 4.5. In another embodiment, 1 ≤ x ≤ 4, 2 ≤ y ≤ 7, or 1 ≤ z ≤ 4 may be satisfied.

Also, the first light absorbing layer 91 may be a mixture of at least one of black titanium, black titanium-carbon, and black carbon and a resin. Alternatively, the first light absorption layer 91 may be a mixture of at least one of black titanium oxide, black titanium-carbon oxide, and black carbon oxide and a resin.

For example, the ratio (M1:M2) of the weight of the resin (M1) and the weight of the black material (M2) may be 1:2 to 1:3. For example, the black material may be at least one of black titanium, black titanium-carbon, and black carbon. Alternatively, for example, the black material may be at least one of black titanium oxide, black titanium-carbon oxide, and black carbon oxide.

Alternatively, the thickness of the first light absorption layer 91 may be 0.5 micrometers or more and 10 micrometers or less. When the thickness T1 of the first light absorption layer 91 is less than 0.5 micrometers, the effect of the black coating is insignificant, and thus the flare reduction effect described later cannot be obtained. When the thickness T1 of the first light absorption layer 91 is greater than 10 micrometers, the characteristics of the lens may be affected, resulting in deterioration of resolution and interference with lens assembly. In another embodiment, the thickness of the first light absorption layer 91 may be greater than or equal to 1 micrometer and less than or equal to 5 micrometers.

A particle size of the black material included in the first light absorption layer 91 may be 0.05 micrometer or more and 2 micrometer or less. In another embodiment, the size of the particles of the black material included in the first light absorption layer 91 may be greater than or equal to 0.1 micrometer and less than or equal to 1 micrometer.

In order to use it as a coating material, the smaller the size of the black material, the more advantageous it is. This is because as the uniformity, that is, the density, of the coating increases, diffuse reflection of light decreases. However, when the particle size of the black material is less than 0.05 microns, the effect of light absorption may be rapidly reduced.

When the black material is formed of large-sized particles, the more irregular the surface coating is, the more diffused reflection occurs and the light is reflected in all directions, so the flare phenomenon can be severe. That is, when the particle size of the black material exceeds 2 micrometers, diffuse reflection occurs easily and light is reflected in all directions, so flare may become severe.

The lens module 400 may further include a stopper 45 disposed on the first lens 42A and a second light absorbing layer 92 disposed on the stopper 45 . The stopper 45 may be disposed on an upper surface of the first lens 42A and may serve to protect the lens array 401 from external impact.

The lens barrel 403 may be formed of an injection molding material. For example, the lens barrel 403 may be formed of a resin or plastic material. For example, the lens barrel 403 may be formed of polycarbonate or liquid crystal polymer (LCP).

In general, a spacer made of a metal material and a lens barrel made of an injection-molded material do not absorb 100 percent (%) of light. Accordingly, while light introduced into the lens barrel from the outside reaches the image sensor, the light is reflected by the spacer and the lens barrel, and as a result, flare or ghost, which is noise, may occur. In particular, when the length of the lens barrel in the direction of the optical axis is long, such as in a zoom camera device, the path of light to the image sensor is long, so light is reflected a lot by the spacer and the lens barrel, which causes flare or ghosting. ) phenomenon may occur, and image deterioration of the camera device may occur.
