Optical imaging lens assembly and image capturing device

An optical imaging lens assembly comprising, in order from an object side to an image side:

• a first lens element with positive refractive power having a convex object-side surface;
• a second lens element with negative refractive power having a concave object-side surface and a convex image-side surface;
• a third lens element having positive refractive power;
• a fourth lens element having refractive power;
• a fifth lens element having refractive power, wherein both of an object-side surface and an image-side surface of the fifth lens element are aspheric;
• and
• a sixth lens element with negative refractive power having a concave object-side surface and a concave image-side surface, wherein both of the object-side surface and the image-side surface of the sixth lens element are aspheric, and at least one of the object-side surface and the image-side surface of the sixth lens element has at least one inflection point;
• wherein the optical imaging lens assembly has a total of six lens elements with refractive power, a curvature radius of the object-side surface of the sixth lens element is R11, a curvature radius of the image-side surface of the sixth lens element is R12, an axial distance between the object-side surface of the first lens element and the image-side surface of the sixth lens element is Td, a curvature radius of the image-side surface of the second lens element is R4, and the following conditions are satisfied:
• −1.0<(R11+R12)/(R11−R12)<0.65;
• and
• −3.0<Td/R4<0.
