Let $D$ be a Carathéodory domain. For $1\leq p\leq \infty $, let $L^p(D)$ be the class of all functions $f$ holomorphic in $D$ such that $\|f\|_{D,p}=[\frac{1}{A}\int\int_{D}^{}|f(z)|^p\,dx\,dy]^{1/p}\infty $, where $A$ is the area of $D$. For $f\in L^p(D)$, set $$ E_n^p(f)=\inf _{t\in \pi _n} \|f-t\|_{D,p}\,; $$ $\pi _n$ consists of all polynomials of degree at most $n$. In this paper we study the growth of an entire function in terms of approximation error in $L^p$-norm on $D$.
